Best Longevity Doctors in San Francisco: 10 Physicians Compared (2026)

San Francisco, the Peninsula, and Marin will all quantify anything. Sleep latency, HRV, glucose curves, protein grams, the exact wattage of a Wednesday morning hill repeat up Twin Peaks, or, if you're coming from the north, the climb up Mount Tam.

Then you sit down for your annual physical, and somebody with nine minutes and a standard lipid panel tells you everything looks fine while you feel like you're running on a dying battery.

That gap is the entire reason people across the Bay Area go looking for a longevity doctor. The market has responded enthusiastically, expensively, and without publishing prices, and it now spans three counties: San Francisco proper, the Peninsula (San Mateo, Menlo Park, Palo Alto), and Marin. Of the ten practices profiled below, only two publish a price on their own site.

Here is what nobody puts on their homepage: four completely different kinds of business are selling themselves under the same word. A genomics-and-imaging assessment center, a concierge internist, a hormone clinic, and a regenerative orthopedics practice are not competitors. They're different products. Buying the wrong one is how smart people end up $12,000 lighter with a beautiful PDF and nobody answering the phone in March.

What follows is how to pick the right lane, verify the license behind the logo using rules specific to California, tell which tests on the menu are guideline-backed and which are still experiments, and hold your new doctor to a standard that actually matters: what exists ninety days after you pay.

Four Different Businesses Are Selling You One Word

The short version, before you open a single clinic website:

1. There is no ABMS-recognized specialty in longevity medicine. Verify a primary board certification in internal, family, or preventive medicine first, and treat "longevity certified" as continuing education, not credentialing.
2. Pick your lane before your clinic. Diagnostics-first assessment, ongoing preventive membership, hormone and age management, and regenerative orthopedics are four different products at four different prices.
3. The practices below span San Francisco, the Peninsula, and Marin, from Union Square and Pacific Heights to San Mateo, Menlo Park, and Mill Valley. Pick one you can actually get to, because the best longevity care involves repeat visits. Confirm the address before you commit to a year of follow-ups.
4. Expect cash-pay. Memberships and advanced imaging are rarely covered. Ask for itemized pricing in writing before your first appointment.
5. Judge the clinic at day 90, not day 1. A named physician reviewing your results, a written plan with target numbers, one intervention actually started, and a scheduled retest. That's the bar.
6. You may not need any of this. Before you spend, read the zero-budget starting point and the hospital-system alternative below. For a lot of readers, that's the correct answer.

What A Longevity Doctor In San Francisco Actually Does: And What No Honest One Promises

Before you compare clinics, you need a clean definition, because the word is doing an enormous amount of unearned work in this city.

A longevity doctor is a licensed physician who uses advanced testing, risk stratification, and ongoing follow-up to reduce your future disease risk before symptoms appear. That's it. Not immortality. Not age reversal. Risk, measured earlier and managed harder than standard care bothers to.

Longevity Medicine Versus Your Kaiser, Sutter, Or UCSF Primary Care Doctor

Your regular doctor is not bad at their job. They are working inside a system built for a different job.

Standard primary care is reactive and threshold-driven. It waits for a number to cross a line that triggers a diagnosis code, then treats. It's screening-interval medicine, and for population health it works reasonably well.

Longevity medicine claims to start earlier and measure more precisely. More attention to particle counts than cholesterol totals. More attention to fasting insulin than fasting glucose. More attention to what your cardiorespiratory fitness percentile says about the next twenty years than what your BMI says about today. Whether a given clinic actually delivers that is what the rest of this page is about.

The honest version is boring in the right ways. More measurement, tighter follow-up, less magical thinking.

Longevity Doctor, Functional Medicine Doctor, Concierge Doctor, Med Spa: Sorting The Four

These get blended constantly, and the differences are real:

1. Longevity medicine: centers on risk reduction and guideline-anchored biomarkers, with a bias toward prevention of cardiovascular disease, metabolic disease, cancer, and cognitive decline.
2. Functional medicine: centers on root-cause and systems-based treatment of existing symptoms. Often overlapping, sometimes excellent, but a different organizing question.
3. Concierge medicine: describes a payment and access model, a membership fee for a small panel and direct physician access. It says nothing about clinical philosophy. A concierge doctor may or may not practice longevity medicine.
4. Med spas and wellness centers: sell procedures and aesthetics. Some now bolt on hormone panels and IV drips. That is not longevity medicine.

The Foundation Nobody Can Sell You

Here's the uncomfortable part for a $20,000 program: the National Institute on Aging keeps saying the same unglamorous thing. Its guidance on what we know about healthy aging puts physical activity, nutrition, sleep, limiting alcohol, and proactive management of your own care at the center of the whole thing.

A good longevity clinic builds on that foundation and helps you execute it with better data. A bad one sells you an infusion menu and hopes you don't notice you still sleep six hours and never lift anything heavy.

Do This Now: Write down the one health outcome you actually want changed in twelve months, not "optimize," a specific thing. Cardiovascular risk. Visceral fat. Perimenopause symptoms. A knee. That sentence is now your filter for every clinic below.

The Version That Costs Nothing (Start Here)

Most people reading this will not spend $12,500, and most people reading this don't need to. Before you price a single membership, ask your existing primary care doctor for the following. Much of it is covered by insurance, and it captures a large share of the useful signal in an expensive assessment:

1. Lipoprotein(a), once: The 2026 ACC/AHA dyslipidemia guideline now recommends measuring Lp(a) at least once in every adult's lifetime, the first time a US guideline has made that a universal recommendation. It's largely genetic and largely fixed, so one measurement is enough.
2. A standard lipid panel, and ask whether apolipoprotein B is appropriate for you (more on that below).
3. Fasting insulin, alongside fasting glucose. Insulin resistance shows up years before glucose drifts.
4. Blood pressure, measured properly: seated, rested, correct cuff size, repeated. 
5. A sleep assessment if you snore or wake unrefreshed: This is the single most commonly missed high-impact finding in otherwise healthy adults.

If your doctor won't order Lp(a), that's now a reasonable thing to push on, because a major US guideline recommends it. If you've done all five and still want more depth, then the rest of this page is for you.

That single sentence from the exercise above determines which of four lanes you belong in.

The Four Lanes Of Longevity Care In The Bay Area

Sorting the market by lane instead of by brand will save you the most money and the most disappointment, in that order.

Lane 1: Diagnostics-First Executive Assessment

A one-shot, high-intensity baseline. Whole genome sequencing, full-body MRI, cardiac CT, DEXA, VO2 max, extensive labs, all compressed into one or two days, followed by a report and a consultation.

1. Strength: unmatched breadth of data in a short window.
2. Weakness: the model is built around the assessment, not the year that follows. Longitudinal management is often thinner than the price implies.
3. Price posture: five figures.

Lane 2: Physician-Led Preventive Membership And Concierge Care

A named physician, a small patient panel, an annual membership, and continuity. Testing is more targeted and gets repeated.

1. Strength: the relationship, which is the actual mechanism by which numbers move.
2. Weakness: less on-site imaging horsepower; advanced scans get referred out.
3. Price posture: annual membership plus outside testing costs.

Lane 3: Hormone And Age-Management Medicine

Perimenopause, menopause, andropause, thyroid, bioidentical hormone replacement, and increasingly peptides and GLP-1s.

1. Strength: for the right patient, hormone care is legitimate medicine that dramatically changes quality of life, and this lane does it with more attention than a rushed OB/GYN or GP visit.
2. Weakness: it is also the lane where the "testosterone mill with better branding" problem lives.
3. Price posture: consult plus ongoing medication and monitoring.

What a competent perimenopause workup looks like, since this is the query that sends most people into Lane 3: A real evaluation starts with symptoms and timing, not a hormone panel in perimenopause. Day-to-day hormone levels swing so much that a single draw often tells you very little, and a clinician who leads with a lab result rather than a history is working backwards. Expect a thorough symptom inventory (cycle changes, sleep, mood, vasomotor symptoms, joint pain, genitourinary symptoms), a review of cardiovascular and breast cancer risk, thyroid and ferritin as differentials, and a clear conversation about the risks and benefits of hormone therapy for your risk profile. A hormone mill looks different: a panel first, a pellet or a protocol second, and a rapid move to a package price. If you leave the first visit with a treatment plan and no history-taking, you learned something.

On GLP-1s: Semaglutide and tirzepatide have moved into longevity clinics quickly, and for people who meet the clinical criteria, they are legitimate, well-studied drugs with real cardiometabolic benefits. Two questions separate a responsible prescriber from an opportunistic one. First: is this the FDA-approved branded product, or a compounded version? Compounded GLP-1s exist in a shifting regulatory space and are not the same product. Second: what's the plan for muscle mass? Rapid weight loss without a protein and resistance-training plan costs you lean tissue, which is the opposite of what you came for. A clinic that has no answer to the second question is selling weight loss, not healthspan.

Lane 4: Regenerative And Orthopedic Longevity

Image-guided orthobiologic injections, joint preservation, non-surgical management of chronic musculoskeletal injury.

1. Strength: genuinely relevant to healthspan, because the thing that ends most people's training is a joint, not a lipid panel.
2. Weakness: it is orthopedics, not internal medicine. It will not manage your ApoB.
3. Price posture: per-procedure.

If your goal is…	Start in this lane
A complete one-time risk baseline you've never had	Lane 1 diagnostics-first assessment
A doctor who will manage your numbers for the next decade	Lane 2 physician-led membership
Perimenopause, menopause, andropause, or thyroid symptoms	Lane 3 hormone and age management
A knee, shoulder, or hip that's ending your training	Lane 4 regenerative orthopedics
Cardiovascular risk specifically, and nothing else	Lane 2, or a preventive cardiologist directly
Coordination with your existing records and insurance	A hospital-system executive health program (see below)

Do This Now: Pick your lane before you open a single clinic website. Then judge every clinic only against the others in that lane. Comparing a $15,000 imaging assessment to a $3,000 concierge membership is comparing a home inspection to a general contractor.

The Option Nobody In This Market Advertises: Your Own Health System

Before the boutique list, the alternative that boutique clinics have no incentive to mention.

Several Bay Area academic and hospital systems, among them UCSF, Stanford Health Care, and Sutter and its affiliated groups, run executive health, advanced preventive, or comprehensive physical programs. Availability, naming, and content change from year to year, so the only reliable move is to call your own system's patient services line and ask directly whether they offer one and what it includes.

What you generally trade, in both directions:

1. You give up imaging breadth and speed. Hospital programs are more conservative about full-body MRI and multi-cancer blood tests, often deliberately, because the institution carries the downstream cost of chasing a false positive.
2. You get a program sitting inside the system that already holds your records, already has your specialists, and already bills your insurance. When something abnormal turns up, the referral is internal, and the follow-up is covered.

For a large share of people who type "longevity doctor San Francisco" into a search bar, this is the correct first phone call. It is slower, less impressive, and considerably cheaper. If it turns out to be too conservative for what you want, the clinics below are still there.

Longevity Doctors And Clinics In San Francisco And The Bay Area, Grouped By Goal

What follows is organized by fit, not by rank. Every detail comes from each practice's own published materials or the named public sources cited. The list spans all three counties in this guide's coverage area: San Francisco, the Peninsula, and Marin. An address is noted for every entry, so check the one closest to you before booking. Verify pricing and staffing directly; this market moves.

My Doctor Medical Group, Union Square

Lane 1, with a door into Lane 2. The deepest one-time workup on this list that's run by the same physicians you can keep seeing afterward.

1. Clinic: My Doctor Medical Group
2. Address: 450 Sutter St, Room 840, San Francisco, CA 94108
3. Phone: (415) 963-4431
4. Website: mydoctorsf.com
5. Specialties: executive health evaluation, concierge internal and family medicine, advanced lipid testing (NMR particle analysis, Lp(a), ApoB), CT coronary calcium score, carotid CIMT ultrasound, exercise stress testing, hereditary cancer and cardiovascular genetic panel, home sleep study, multi-cancer early detection blood test; optional add-ons include VO2 max, DEXA, CT coronary angiography, full-body MRI with brain volumetrics, and whole genome sequencing
6. Best for: someone who wants a thorough baseline from a physician who takes a history first, and who may want to stay with the same team afterward instead of taking a report back to a rushed primary care visit
7. Pricing: The executive evaluation starts at $12,500 and includes more than four hours of physician time spread across a video intake, a testing day, an in-person exam, and a sixty-minute results review. Add-ons are priced individually after the intake. The bundled evaluation is not billed to insurance; the practice notes it may qualify for HSA/FSA reimbursement, which is your plan administrator's call. Appointments typically book four to six weeks out. Confirm current pricing before booking.

Who's behind it: Founder and medical director Paul Abramson, MD, earned his medical degree at UCSF and a master's in engineering at Stanford, and the practice lists him as board-certified in family medicine and addiction medicine, with a clinical assistant professor appointment at UCSF.

One thing to price honestly: the evaluation's multi-cancer blood test and the optional full-body MRI both sit in the territory this page's evidence section treats with caution for low-risk adults. The practice's own framing is that add-ons are recommended by clinical profile rather than sold as a menu, which is the right posture. Hold them to it on the intake call.

A note on the address: this is the same building as California Longevity & Vitality Medical Institute, a different practice on a different floor.

Translation: this is the only Lane 1 option on this list, and one where the people who take the photograph can also shoot the film. Decide at the wrap-up visit whether you want the second part.

Savant Wellness, San Francisco

Lane 2. The longest-running concierge internal medicine relationship on this list, and the product is the relationship, not an event.

1. Clinic: Savant Wellness
2. Address: 1 Shrader St, Suite 550, San Francisco, CA 94117 (NoPa, at the Panhandle)
3. Phone: (415) 967-6610
4. Website: savantwellness.com
5. Specialties: concierge internal medicine, preventive and longevity focus, comprehensive annual assessment, weight management, epigenetic age testing, direct physician phone access, deliberately small panel
6. Best for: someone who wants a real doctor relationship inside San Francisco rather than a diagnostic event, and who values same-week access over an on-site MRI
7. Pricing: Savant does not publish a figure. Membership is an annual subscription that includes intake, a personalized plan, ongoing follow-up, care coordination, app messaging, and direct phone access, with no additional fees billed for membership services. Third-party costs, including labs, imaging, and prescriptions, are billed separately by outside providers. Medicare and commercial insurance do not reimburse the fee; some FSA and HSA plans may, and that is your administrator's call. The practice offers a no-cost meet-and-greet before you commit.

Dr. Mark J. Savant, MD, is a San Francisco native who earned his medical degree at the Medical College of Wisconsin in 1994 and completed his internal medicine residency at Santa Clara Valley Medical Center. He started Savant Medical Group in 2001 and holds hospital affiliations at St. Mary's Medical Center and St. Francis Memorial Hospital. These details come from the practice's own site; confirm the license and primary board certification yourself through the Medical Board of California, which takes about a minute.

One thing to price honestly: the membership includes two biological age tests a year, and by the evidence standard laid out later on this page, that is a trend line to watch rather than a number to steer by. Ask that Lp(a) and a full lipid panel go on the panel too.

Translation: this is the shape of practice where day 90 actually happens. The scan is a photograph; the relationship is the film.

Peninsula Doctor, Menlo Park

Lane 2. The Peninsula counterpart to Savant Wellness: a relationship, not an event, from a practice that has been doing concierge primary care for two decades.

1. Clinic: Peninsula Doctor
2. Address: 401 Burgess Drive, Suite A, Menlo Park, CA 94025
3. Phone: (650) 800-3365
4. Website: peninsuladoctor.com
5. Specialties: concierge family medicine, preventive medicine, women's health, longevity care, same-day visits, direct physician access around the clock, home and office visits when appropriate, a patient panel capped at 100 per physician
6. Best for: someone on the Peninsula or in Silicon Valley who wants a primary care physician who also manages long-term risk, and who values access and continuity over on-site imaging
7. Pricing: Not published. Membership covers primary care, preventive care, women's health, and longevity care with no per-visit fees. The practice does not bill insurance or Medicare and recommends keeping insurance for hospital care, specialists, and outside testing. Ask which longevity tests are included in the membership and which are billed separately by outside labs and imaging centers.

Who's behind it: Founder Ian Kroes, MD, earned his medical degree at Stanford and a degree in applied physics at UC Berkeley, and has practiced family medicine in Menlo Park for more than twenty years. Family physicians Judy Kim, MD (Georgetown) and David Hiroshima, MD (Stanford) round out the clinical team. Co-founder Sabina Kroes runs business and operations. Confirm each physician's license and primary board certification through the Medical Board of California.

One thing to ask directly: Longevity care is one of four service lines here rather than the whole practice, which is the honest shape of most good concierge medicine. The questions that tell you how deep it goes are the ones from the checklist below: whether Lp(a) is on the first panel, when apoB gets added, and what happens at day 30, 60, and 90 after results.

Translation: this is a family doctor with time. For a lot of people, that's the longevity intervention they were actually missing.

LifeLab Concierge Medicine, Pacific Heights

Lane 2, with standalone testing. The practice on this list most closely built around the evidence this page cares about: VO2 max, metabolic health, and retesting.

1. Clinic: LifeLab Concierge Medicine
2. Address: 2100 Webster Street, Suite 401, San Francisco, CA 94115
3. Phone: (415) 707-3898 (call or text)
4. Website: lifelabconciergemedicine.com
5. Specialties: metabolic medicine and healthy aging, VO2 max testing, resting metabolic rate, body composition, advanced cardiometabolic labs, executive physicals, medically supervised weight loss including GLP-1 care, full concierge primary care
6. Best for: someone whose main concern is insulin resistance, weight, cardiovascular risk, or fitness, and who wants a physician who treats those numbers as a plan rather than a report
7. Pricing: The entry point is a $249 metabolic and weight-loss assessment covering resting metabolic rate, body composition, blood work as needed, and a medical review. From there, patients can join a medical weight-loss program for a monthly fee, book standalone VO2 max or metabolic testing to take to their own doctor, or apply for one of a limited number of full concierge memberships. Membership and program fees are not published. Confirm current pricing before booking.

Who's behind it. Founder Eric Pifer, MD, earned his medical degree at the Medical College of Pennsylvania and trained in internal medicine at Temple University Hospital, where he later served as chief resident. He taught as an assistant professor of medicine at the University of Pennsylvania and held chief medical officer roles in several California health systems before building a concierge program in San Francisco in 2022.

Two questions to ask on the call: First, the practice uses an AI-assisted analysis system alongside physician judgment, so ask what it does and who signs off on the plan. Second, because GLP-1 care is a core service, ask this page's two standard questions: branded or compounded, and what's the plan for muscle? LifeLab's own materials name muscle preservation during weight loss as a goal, which is the right starting point.

A note on the address: this is the same building as Physical Longevity's San Francisco office, a different practice on a different floor.

Translation: this is Zone 2 and fasting insulin run as medicine. If your honest goal is metabolic, start here before you price a scan.

Interactive Wellness, Menlo Park

Lane 2. A four-physician internal medicine practice with Stanford ties, for people who want the relationship and the referral network in the same place.

1. Clinic: Interactive Wellness Concierge Medicine
2. Address: 401 Burgess Drive, Suite B, Menlo Park, CA 94025
3. Phone: (650) 325-9906
4. Website: interactivewellness.com
5. Specialties: concierge internal medicine, preventive and longevity screening, extended physician visits, same-day appointments, coordination with Stanford and Bay Area specialists, direct physician phone and email access, after-hours on-call coverage
6. Best for: someone on the Peninsula who wants an internist, not just a testing program, and who values a direct line into the Stanford specialist network
7. Pricing: Not published. Membership covers extended visits, preventive and longevity screening, specialist coordination, and direct physician access.

Who's behind it: The practice's physicians are Lance Downing, MD, Seth Weissman, MD, Bonnie Rosenberg, MD, and Benny Gavi, MD. Dr. Downing is a Stanford-trained internist with a clinical faculty appointment, and he publishes physician-written articles on lipid screening, atherosclerosis, GLP-1 medications, and sleep.

One thing to ask directly: "longevity screening" can mean anything from a standard physical to a full advanced panel. Ask what the first-year screening actually includes, whether Lp(a) is on it, and when apoB and a coronary calcium score get added.

A note on the address: Peninsula Doctor is in the same building, in Suite A. They're separate practices, and both are worth a meet-and-greet if you're choosing on the Peninsula.

Translation: an internist with time and a Stanford rolodex. That's the combination that gets an abnormal result from "worth watching" to "handled."

Bay Area Wellness Center, San Mateo

Lane 2, practiced as functional medicine. A board-certified internist with a root-cause approach, and a different organizing question than the rest of this list.

1. Clinic: Bay Area Wellness Center
2. Address: 101 S. San Mateo Drive, San Mateo, CA 94401
3. Phone: (650) 692-7545
4. Website: diabesitydoc.com
5. Specialties: functional medicine, diabetes and obesity care, dementia risk and cognitive care, longevity care, nutrition counseling, medical weight loss, thyroid and hormonal concerns
6. Best for: someone with prediabetes, metabolic syndrome, or a family history of dementia who specifically wants a functional medicine approach from a physician with conventional internal medicine training
7. Pricing: Not published. The practice runs on a private-practice membership agreement. Ask for the membership terms, the cost of specialty functional lab testing (usually cash-pay), and what a follow-up visit costs outside the membership, all in writing. Office hours are Monday, Tuesday, Thursday, and Friday, with Wednesday by appointment.

Who's behind it. Frank Tortorice, MD, lists board certification in internal medicine through the American Board of Internal Medicine and certification from the Institute for Functional Medicine.

The disclosure: This page separates functional medicine from longevity medicine. Functional medicine starts from existing symptoms and root causes, longevity medicine starts from future risk. This practice is functional medicine first, with longevity care as one service line.

Translation: a real internist who practices functional medicine. Go for the metabolic and cognitive work, and keep this page's evidence table in hand when the recommendations arrive.

California Longevity & Vitality Medical Institute, Union Square

Lane 3. A hormone practice with a long conventional career sitting behind it.

1. Clinic: California Longevity & Vitality Medical Institute
2. Address: 450 Sutter St, Suite 2310, San Francisco, CA 94108
3. Phone: (415) 619-3021
4. Website: longevitymd.net
5. Specialties: age management medicine, bioidentical hormone replacement, andropause, menopause and perimenopause, thyroid, growth hormone deficiency, peptide protocols, diet and nutrition counseling
6. Best for: someone whose primary complaint is hormonal and who wants a physician with a long conventional practice history behind the age-management focus
7. Pricing: Not published. Expect a consultation fee plus ongoing medication and monitoring costs, typically monthly. The practice works in person rather than by telehealth, which means office visits are part of the ongoing cost. Ask for itemized pricing in writing, including what a follow-up and a repeat hormone panel cost outside any package.

Medical director Dr. Rachel Frankel Meek, DO, MPH, graduated from the College of Osteopathic Medicine of the Pacific at Western University of Health Sciences in 1987, completed an internship and pediatrics residency at Kaiser Oakland, and spent more than thirteen years as a partner at Kaiser Permanente Medical Group before moving into age management.

She is a DO, so her license sits with the Osteopathic Medical Board of California, not the Medical Board of California. That's where to confirm it.

Radiant Health, Cow Hollow

Lane 3. In the city, on Lombard, and a different license than the others on this list.

1. Clinic: Radiant Health SF
2. Address: 2137 Lombard St, 2nd Floor, San Francisco, CA 94123 (second location: 2400 Las Gallinas, Suite 140, San Rafael, CA 94903, useful if you're in Marin)
3. Phone: (415) 590-2899
4. Website: radianthealthsf.com
5. Specialties: bioidentical hormone replacement, thyroid support, menopause and perimenopause, PCOS and adrenal support, gut health, medical and GLP-1 weight loss, NAD+ therapy, peptide therapy, TruAge epigenetic testing, specialty functional lab testing
6. Best for: someone specifically seeking naturopathic hormone care inside San Francisco who understands exactly what license they are hiring
7. Pricing: Not published. The practice opens with a complimentary health strategy call, after which visit fees, lab panels, and program costs are quoted individually. Specialty functional testing is generally cash-pay. Ask for the full itemization before the first appointment.

Clinic director Dr. Kristy Vermeulen, ND, leads a team that includes Dr. Nazanin Safaei, ND, and a functional nutrition health coach.

The license clarification the marketing does not make obvious. This is a naturopathic practice. California NDs are licensed by the state's naturopathic medicine regulator, not the Medical Board of California. It's a legitimate license with a real scope. Under California Business and Professions Code §3640.7(b), NDs may independently prescribe and administer natural and synthetic hormones, while most other prescription drugs require physician supervision. An ND needs a DEA number to prescribe testosterone or hCG. Verify any ND at naturopathic.ca.gov, not at the Medical Board.

JYZEN, Mill Valley

Lane 3, with a heavy diagnostics layer. The only practice on this list headquartered in Marin, and built around multi-month in-person programs.

1. Clinic: JYZEN
2. Address: 100 Shoreline Hwy, Suite 210A, Mill Valley, CA 94941
3. Phone: (415) 729-0449
4. Website: jyzen.com
5. Specialties: integrative and functional medicine, hormone balancing, peptide therapy, metabolic assessment, advanced blood, urine, and stool panels, biological age testing, cardiovascular risk profiling, movement and performance testing, EEG brain mapping, IV therapies
6. Best for: a Marin or North Bay resident who wants an integrative, program-based approach and can commit to regular in-person sessions
7. Pricing: Not published. Programs are structured over months rather than sold as single visits, so ask for the total program cost, what a standalone follow-up costs, and what a repeat lab panel costs outside the program, all in writing, before you enroll.

Who's behind it: Co-founder and chief medical officer Beth McDougall, MD, has more than twenty-five years in integrative medicine. The clinical staff is multidisciplinary and includes integrative, functional, naturopathic, osteopathic, and sports medicine clinicians. That mix means the person you see may hold an MD, a DO, or an ND. Ask which one before booking, and verify each through the right board: the Medical Board of California for MDs, the Osteopathic Medical Board of California for DOs, and naturopathic.ca.gov for NDs.

Translation: the diagnostics and the program structure are the reason to go. Decide in advance which parts of the menu you're there for, and hold that line.

Physical Longevity, San Francisco

Lane 4. Read this entry carefully, because the brand and the appointment line are two different things.

1. Clinic: Physical Longevity (a four-physician collaboration); its San Francisco physician practices at RegenCore Method
2. Address: 2100 Webster St, Suite 424, San Francisco, CA 94115 (Pacific Heights; a second office in Palo Alto shares the line)
3. Phone: (650) 328-4411
4. Websites: regencoremethod.com
5. Specialties: ultrasound- and fluoroscopy-guided orthobiologic injections, PRP, bone marrow aspirate concentrate, adipose tissue transfer, dextrose prolotherapy, nerve hydrodissection, ultrasound-guided tendon debridement; knee, hip, shoulder, elbow, ankle, foot, and spine
6. Best for: an athlete with a specific joint problem that is ending their training. Not a substitute for metabolic or cardiovascular care; this lane will not manage your ApoB
7. Pricing: Per-procedure and not published. The intake is a concierge evaluation, and no referral is required. Orthobiologic injections are rarely covered by insurance. Get the evaluation fee and the per-procedure fee quoted separately before you book.

Dr. Rowan V. Paul, MD, graduated from Albany Medical College in 2005, is a board-certified family physician with fellowship training in sports medicine, and spent ten years as a full partner in a San Francisco orthopedic surgery group before leaving to practice regenerative orthopedics non-surgically. He is a clinical assistant professor at Dartmouth's Geisel School of Medicine, head company physician for the San Francisco Ballet, and sat on the national SAFE expert panel that published consensus guidelines on bone marrow aspirate concentrate. That's the one credential on this list you can verify against a published paper rather than a bio page.

Who I Left Out, And Why

Omission here isn't always a quality judgment.

Med spas and aesthetic practices with a hormone add-on were excluded because they're a different lane wearing longevity vocabulary. Peptide-forward telehealth clinics were excluded because the underlying regulatory status of several popular compounds has changed more than once in recent years, and I'm not sending readers toward a moving target. Practices that don't publicly name a lead clinician were excluded on principle; if I can't tell you who's responsible for your care before you book, the page hasn't done its job.

And national chains, venture-backed platforms, and hospital-owned programs were left out on purpose. They have marketing budgets and review footprints that don't need another assist, and this guide is more useful pointing you toward independent, physician-led practices you won't find on the first page of an ad auction. The hospital-system route is covered separately above.

How These Clinics Were Selected, And How They Were Verified

Every criterion below was applied before any clinic was written up, and applied identically.

1. A publicly identifiable lead clinician with a verifiable license and a stated primary training background.
2. A published, specific service menu, not a page of adjectives.
3. A clear care structure: what the intake includes and what happens afterward.
4. A physical Bay Area location disclosed on the practice's own site.
5. Lane clarity: the practice does one thing well enough to recommend it for that thing.

How this page was verified. Every price is taken from the practice's own published materials; where a practice publishes no price, the entry says so rather than estimating. No practice was contacted for comment, and no practice reviewed this page before publication.

Now for the part that protects you regardless of which one you choose.

The California Trust Layer: Verify A Longevity Doctor In Ten Minutes

This is the section that matters most, because California has specific rules that make credential-checking faster here than almost anywhere else, and most people don't know they exist.

Why "Board Certified In Longevity Medicine" Doesn't Mean What You Think In California

The American Board of Medical Specialties recognizes 24 member boards. Internal medicine. Family medicine. Preventive medicine. Cardiology sits under internal medicine as a subspecialty.

Longevity medicine is not one of them. Neither is anti-aging medicine.

Private organizations do issue longevity and anti-aging certifications, and completing one is not fraud; it's continuing education, and some of it is substantive. But it is not equivalent to residency training plus an ABMS board exam, and California law draws that line explicitly.

Under California Business and Professions Code §651(h)(5)(C), a physician licensed by the Medical Board of California generally may not advertise as "board certified" unless the certifying board is an ABMS member board, holds an ACGME-accredited postgraduate training program, or was approved by the Medical Board of California before January 1, 2019. The Medical Board's own practice information page confirms that its authority to approve non-ABMS boards was removed effective that date.

One nuance that matters, so you don't over-read this: The law does not prohibit a physician from advertising that they specialize in something, regardless of certification status, and it doesn't restrict terms like "diplomate," "member," or "approved by." A San Francisco clinic saying "we specialize in longevity medicine" is doing nothing wrong. A clinic saying "board-certified in longevity medicine" is making a claim that, under state law, does not carry the weight most patients assume.

What you're actually looking for is a primary board certification from an ABMS member board (or, for a DO, an ABMS or AOA board) in internal medicine, family medicine, preventive medicine, endocrinology, cardiology, or OB/GYN, plus demonstrated longevity focus on top of it.

Look Up The License, Not The Logo

California physicians are licensed by one of two boards, depending on their degree. MDs are licensed by the Medical Board of California; DOs are licensed by the Osteopathic Medical Board of California. Both are searchable for free through the state's DCA License Search. Check the letters after the doctor's name first, then search the right board. Confirm the license is current, confirm the primary specialty, and check for any disciplinary actions.

Naturopathic doctors are searchable through the California Board of Naturopathic Medicine. Nurse practitioners through the Board of Registered Nursing. Different boards, different scopes, all public.

Ask Who Is Actually Treating You

This changed recently, and almost nobody knows it.

California's AB 890 created two new nurse practitioner categories: 103 NPs and 104 NPs. The 103 pathway has been available since 2023 and permits practice without standardized procedures inside a group setting that includes a physician.

As of January 1, 2026, qualifying nurse practitioners became eligible for 104 status, which permits fully independent practice outside a group setting without physician supervision, but only within the population focus of their qualifying national certification (family, adult-gerontology, neonatal, pediatrics, women's health, or mental health). That limitation is worth knowing: it means a given NP's independent scope may or may not cover what you're coming in for.

This is not a knock on nurse practitioners, many of whom are outstanding clinicians. It's a disclosure question. If a clinic's marketing is built around a physician's credentials but your actual visits are with someone else, you should know that before you sign, not after.

Find Out Who Owns The Clinic

In California, a medical professional corporation requires majority physician ownership. Many wellness businesses are structured instead as a management services organization contracting with a small medical group.

This isn't inherently sinister; it's how a lot of modern healthcare is financed. But it shapes incentives. Ask: who decides what gets recommended to me, and is that person a clinician?

Your Five-Step Verification Sequence

1. Find the lead clinician's full name on the clinic's own site. If you can't, stop there.
2. Search the right license board: The Medical Board of California for an MD, the Osteopathic Medical Board of California for a DO. Confirm active status and check discipline. 
3. Identify the primary board certification: Internal medicine, family medicine, preventive medicine, or another ABMS board for an MD; an ABMS or AOA board for a DO. Not "longevity."
4. Ask who conducts your visits: the named physician, an NP, a PA, or a health coach, and get the answer before you pay.
5. Ask for itemized pricing in writing, including what a follow-up visit and a retest cost outside the initial package.

Do This Now: Run steps 1 through 3 on your top two clinics tonight. It takes under ten minutes each. If a practice makes step 1 hard, you've learned everything you need to know.

Credentials tell you who's ordering the tests. Next you need to know which tests are worth ordering.

What The Testing Menu Is Actually Worth: An Evidence-Graded Breakdown

A longevity clinic's menu is not a quality signal. Volume of testing and value of testing are different variables, and being honest about the difference is what separates medicine from merchandising.

Earns Its Money

Lipoprotein(a): Largely genetic, largely fixed, and now a genuinely settled recommendation. The 2026 ACC/AHA multisociety dyslipidemia guideline, published in March 2026, recommends measuring Lp(a) at least once in every adult's lifetime, the first time a US guideline has made universal Lp(a) screening a Class I recommendation. Because it's genetically determined and stable across a lifespan, one early measurement is enough. If yours is high, it changes how aggressively every other cardiovascular lever gets pulled. If a clinic is not measuring this, ask why.

Apolipoprotein B: ApoB counts atherogenic particles directly, one molecule per LDL, VLDL, and Lp(a) particle, whereas LDL-C estimates the cholesterol mass inside them. The 2026 guideline supports selective apoB measurement to refine risk, particularly in people with elevated triglycerides or diabetes, where LDL-C estimates are least reliable. It is directly measured rather than calculated and is not affected by fasting status. This is not a test every adult needs, and a clinic declining to order it for a low-risk patient is not a red flag. But if you have high triglycerides, diabetes, metabolic syndrome, or a family history of early heart disease, it's a reasonable thing to ask about by name.

Fasting insulin and HOMA-IR: Insulin resistance shows up years before fasting glucose drifts. A normal glucose with a high fasting insulin is the metabolic equivalent of a smoke alarm you've been ignoring.

VO2 max and cardiorespiratory fitness: Not a vanity metric. In a Cleveland Clinic study of 122,007 adults published in JAMA Network Open, cardiorespiratory fitness was inversely associated with all-cause mortality, with no observed upper limit of benefit. The adjusted mortality risk for the lowest-fitness group versus the highest was larger than the risk associated with coronary artery disease, smoking, or diabetes in the same analysis. Two caveats worth noting: this was a cohort of patients referred for treadmill testing rather than a healthy general population, and fitness was estimated from treadmill performance rather than measured directly by gas exchange. The direction and magnitude of the finding are robust; the precision of any single number is not.

DEXA: Body composition and visceral fat, plus bone density. Cheap, fast, and it reframes what "weight" means.

Coronary artery calcium score: For the right patient, a direct look at whether the disease is already there. The 2026 guideline supports selective imaging of subclinical atherosclerosis for risk refinement in appropriate patients.

Blood pressure, measured properly: Unglamorous. Enormous.

Useful, With Caveats

CGM is a superb behavioral teaching tool for two to four weeks in a non-diabetic. It is a poor permanent identity. hs-CRP adds inflammatory context but moves with a cold, a hard workout, or a bad week. Sleep testing matters enormously if you snore or wake unrefreshed, and matters little otherwise. Cognitive baselines are worth having in your forties precisely because their value is comparative, ten years later.

Still A Science Experiment

Epigenetic biological age tests. Clinics love the phrase "your exact biological age." The research does not support that confidence. A 2025–2026 analysis of eighteen commonly used clocks found that most are technically reproducible across lab replicates, meaning the same sample tested twice gives a consistent answer, but their biological reliability is much weaker:  estimates shift meaningfully with meals, acute stress, physical exhaustion, and altitude exposure. Different clocks also disagree with each other on the same sample. Reviewers in eBioMedicine have made the same point about commercial wellness use.

Epigenetic clocks are a real and promising research tool. Treated as a motivational trend line over years, they're interesting. Treated as a precise number you paid to move in one quarter, they'll mislead you.

Full-body MRI in low-risk asymptomatic adults. This is the hardest one to say in a city that loves the idea. The American College of Radiology has stated that there is insufficient evidence to justify recommending total body screening for patients with no symptoms, risk factors, or family history suggesting underlying disease, and that no documented evidence shows it prolongs life. The College has issued comparable guidance for screening total-body MRI.

The problem isn't the scan; it's that a sensitive scan in a low-prevalence population finds something very often, and most of those somethings are benign. A BMJ systematic review of whole-body MRI in asymptomatic adults found that among potentially serious incidental findings with follow-up data, only about one in five turned out to have a serious final diagnosis. Published screening series report confirmed cancer detection in roughly 1–2% of scans, against incidental-finding rates that run far higher.

If you have a strong family history or a specific genetic risk, this calculus changes. For a healthy 42-year-old buying peace of mind, understand you may be buying a biopsy and six months of anxiety instead. This is a conversation to have with a physician before you book, not after the report lands.

Most "cellular" IV therapies, including NAD+ infusions, remain thin on human outcome evidence.

Regulated Territory

Peptides: Under federal law, a compounding pharmacy may only use bulk substances meeting specific conditions under FDA's 503A framework. Several popular longevity peptides are not FDA-approved for any human use, lack a USP monograph, and have moved between regulatory categories while agency review continues. That means a clinic's answer to "where does this come from and what's its current federal status?" is a legitimate test of the clinic. Regulatory status here changes faster than any article can track; confirm current status directly before starting any protocol.

Hormones and off-label prescribing are legitimate physician decisions when they follow a diagnosis, a discussion of risks, and a monitoring plan. Be wary when the protocol arrives before the workup.

Test	What it should actually change in your plan
Lp(a)	How aggressively every other cardiovascular lever gets pulled; measure once
ApoB (selective)	Whether you start or intensify lipid-lowering therapy
Fasting insulin / HOMA-IR	Training structure, meal timing, carbohydrate load
VO2 max	Your Zone 2 volume and whether you're doing any real intensity
DEXA	Protein intake and whether you're actually lifting heavy
Coronary calcium score	Whether you're in primary prevention or already treating disease
Epigenetic age	Very little on its own; track it, don't steer by it
Full-body MRI	Depends entirely on your baseline risk; discuss before ordering

Do This Now: Ask any clinic whether Lp(a) is on your first panel. It's now a Class I, once-in-a-lifetime recommendation, and there's no good reason to skip it. If your lipid numbers look fine but your risk profile doesn't, ask whether apoB is appropriate for you and take that conversation to a physician rather than a supplement plan.

What Longevity Care Costs In San Francisco

Nearly nobody publishes numbers, which is precisely why you need bands in your head before the first phone call. All figures below are current as of September 2026; confirm directly, because this market moves fast.

The Price Bands You'll Actually Encounter

1. Targeted advanced testing panel, self-ordered or clinic-ordered: hundreds to low four figures. LifeLab Concierge Medicine publishes a $249 metabolic assessment covering resting metabolic rate, body composition, and a medical review.
2. Concierge or membership primary care with a longevity focus: typically low-to-mid four figures annually, testing often extra.
3. Hormone and age-management programs: consult fee plus ongoing medication and monitoring, usually monthly.
4. Full diagnostics-first assessment with imaging and genomics: five figures. My Doctor Medical Group publishes a starting price of $12,500 for its executive evaluation, with advanced imaging and genome sequencing priced as add-ons.

HSA, FSA, Insurance, And What Rarely Gets Covered

Memberships, elective full-body imaging, and most epigenetic testing are cash-pay. Standard labs and some telehealth visits can sometimes be billed to insurance. Medicare does not reimburse concierge or longevity membership fees.

HSA and FSA funds may cover qualifying medical services, but eligibility is decided by your plan administrator, not the clinic. Two practical points: get itemized coding and confirm before you pay, and ask specifically whether the practice issues superbills or itemized invoices at all. Without itemized documentation, reimbursement gets considerably harder regardless of what your plan allows. 

A Worked First-Year Example, Line By Line

Here's an illustrative composite, not a quote from any clinic named above, and not a recommendation. It's a planning exercise so you can see where the money actually goes.

Line item	Cost
Concierge membership with a physician-led practice	$4,000
Comprehensive advanced lab panel, including Lp(a), full lipids, fasting insulin, hs-CRP, full thyroid	$800
Coronary artery calcium score	$150
DEXA scan, twice	$300
VO2 max test, twice	$500
CGM, one month	$250
Repeat lab panel at month six	$600
Total	~$6,600

That's a first year with two retests, two body composition measurements, and continuous physician access. Compare it against a single five-figure imaging assessment. Neither is wrong. They're different purchases. One is a photograph of this moment; the other is a year of management.

Do This Now: Before you pay anything, ask for the price of three things separately: the intake package, one follow-up visit, and one repeat lab panel. Programs that only quote a bundle are usually optimized for the sale, not the second year.

The First 90 Days Test: The Only Reliable Way To Judge A Longevity Doctor

The intake visit is the easy part. Everybody performs well at the intake visit. The next thirty to ninety days are the real product.

What Should Happen In Weeks One Through Four

Testing gets completed. Results come back. And then this is the whole thing: a named physician sits down with you and interprets them, not a portal notification and a PDF.

You should leave that conversation with a written plan that contains actual target numbers. Not "improve metabolic health." Something like: get a specific lipid marker under a specific threshold, add two Zone 2 sessions a week, lift three times, retest in twelve weeks.

At least one intervention should start. Immediately.

What Should Exist By Day 90

Five things. If any are missing, you have a diagnostics vendor, not a doctor.

1. A written plan with numeric targets, in your possession.
2. At least one intervention started and adjusted at least once.
3. A retest scheduled or completed on the markers that were actually abnormal.
4. A specific human being you can reach with a question and expect an answer from.
5. A clear statement of what you're not doing yet, and why.

A composite illustration, not a real patient, and not a case study. Imagine a 46-year-old software engineer in Noe Valley who pays for a comprehensive assessment. His imaging is clean. His Lp(a) comes back elevated, and his fasting insulin is quietly high despite an LDL-C his old doctor called normal. Week three, a physician walks him through both, explains why an elevated Lp(a) changes the aggressiveness of everything else, and puts three things in writing: a lipid-lowering conversation with a target, two Zone 2 rides a week on top of the hard group ride he already does, and a twelve-week retest. Day 90 arrives. He gets the retest, one number moved, and the plan gets adjusted.

The failure mode I hear about from people who've been through longevity and functional medicine programs is the same story, with day 30 as silence, day 60 as an upsell email for an IV package, and day 90 as a renewal invoice. 

Five Signals That Mean You Should Leave

1. A protocol was recommended before your results came back.
2. Nobody can tell you which clinician is responsible for your care.
3. The follow-up plan is "book whenever you'd like."
4. Supplements sold in-house make up a large share of the recommendations.
5. Anyone uses the phrase "reverse your biological age" as a statement of fact.

One reader's-eye observation: In ten years of talking to people who've bought into this category, the most expensive mistake I hear about is buying the scan and skipping the relationship. A full-body MRI tells you about one Tuesday. A physician who knows your lipid trend across three years tells you about the next twenty. If your budget only covers one of those, buy the second one.

Questions To Ask A San Francisco Longevity Clinic Before You Pay Anything

Copy these. Ask them on the phone, before the tour.

1. Who is the lead physician, and what is their primary board certification?
2. Will I see that physician at every visit, or an NP, PA, or coach?
3. Is your practice a medical corporation, a naturopathic practice, or an NP-owned practice?
4. What exactly is included in the intake package, itemized?
5. What does a follow-up visit cost outside the package?
6. Do you order Lp(a) as standard, and when would you add apoB?
7. What happens at day 30, day 60, and day 90 after my results?
8. Which of your recommended interventions are FDA-approved for the use you're proposing?
9. Do you sell supplements or compounds in-house, and what share of revenue is that?
10. Do you issue superbills or itemized invoices for HSA, FSA, or insurance submission?
11. If I want to leave, do I get my full data set in a portable format?

Question 11 is the one that makes people uncomfortable, which is exactly why it works.

Key Questions Answered

What is a longevity doctor?

A longevity doctor is a licensed physician who uses advanced testing, risk stratification, and ongoing follow-up to reduce future disease risk before symptoms appear. The focus is healthspan, the years you stay strong and functional, rather than treating disease after diagnosis. In practice, that means more attention to biomarkers, body composition, cardiovascular risk, and repeat measurement than standard primary care typically provides.

Is longevity medicine a recognized medical specialty?

No. The American Board of Medical Specialties recognizes 24 member boards, and longevity medicine is not among them. Private organizations issue longevity and anti-aging certifications, and that training can be substantive, but it is not equivalent to an ABMS board certification. Look for a primary board certification in internal, family, or preventive medicine from an ABMS board (or, for a DO, an ABMS or AOA board), with longevity practice built on top of it.

Can a California doctor advertise as "board certified in longevity medicine"?

Generally no. Under California Business and Professions Code §651(h)(5)(C), physicians may not advertise as "board certified" unless the certifying board is an ABMS member board, holds an ACGME-accredited postgraduate training program, or received Medical Board of California approval before January 1, 2019. Osteopathic physicians follow a parallel rule that recognizes American Osteopathic Association boards. Neither pathway recognizes longevity medicine. The law does still permit advertising that a physician specializes in a field.

Are San Francisco longevity clinics actually in San Francisco?

This guide covers San Francisco, the Peninsula, and Marin together. Of the ten practices profiled here, six are inside city limits, two are in Menlo Park, one is in San Mateo, and one is in Mill Valley. Two of the San Francisco practices also have second offices, one in Palo Alto and one in San Rafael. Longevity care works best with repeat visits, so confirm the exact address and your realistic travel time before committing to a year of follow-ups.

How much does a longevity doctor cost in San Francisco?

Expect cash-pay. Targeted advanced testing runs from hundreds to low four figures; one San Francisco practice publishes a $249 metabolic assessment. Concierge memberships with a longevity focus typically run low-to-mid four figures annually. Full diagnostics-first assessments with imaging and genomics run into five figures; one independent San Francisco practice publishes a starting price of $12,500 for its executive evaluation. Always request itemized pricing in writing.

Does insurance cover longevity medicine?

Usually not. Memberships, elective full-body imaging, and epigenetic testing are almost always out of pocket. Some standard lab work and telehealth visits may bill to insurance. HSA and FSA funds sometimes apply, but your plan administrator decides; confirm with them, not the clinic, before paying.

Does Medicare cover a longevity doctor?

No. Medicare does not reimburse concierge or longevity membership fees. Individual services ordered by a participating physician, standard labs, or imaging with a covered clinical indication may still be billed separately. The membership itself is always out of pocket.

What's the cheapest way to start?

Ask your existing primary care doctor for a one-time Lp(a) test, a lipid panel, fasting insulin, and a properly measured blood pressure, plus a sleep assessment if you snore. Most are covered by insurance. That's a large share of the useful signal in an expensive assessment, at a fraction of the price.

Is a full-body MRI worth it if I feel fine?

For low-risk adults without symptoms, risk factors, or relevant family history, the American College of Radiology has said the evidence is insufficient to recommend total body screening. Sensitive scans in low-risk people frequently find incidental abnormalities, most of them benign, which can lead to further imaging, biopsies, and anxiety. If you carry meaningful family or genetic risk, discuss it with a physician first.

Are epigenetic biological age tests accurate?

No, not as a precise number. The same sample tested twice in a lab gives a consistent result, but your score shifts with meals, stress, poor sleep, and hard exercise, and different clocks disagree with each other. Treat them as a research-grade trend line over years, not a number you paid to move in one quarter.

Which tests should a good longevity clinic order first?

Lp(a) once in your lifetime, a full lipid panel, fasting insulin, hs-CRP, a thyroid panel, and blood pressure measured properly. DEXA adds body composition and bone density; VO2 max adds cardiorespiratory fitness. A coronary artery calcium score is appropriate where age and risk warrant it. Ask whether apoB is available; the 2026 guideline supports selective use.

Will I see a physician or a nurse practitioner?

Ask directly, because the answer varies. California's AB 890 created two nurse practitioner pathways, and as of January 1, 2026, qualifying nurse practitioners became eligible for 104 status, permitting independent practice within their certification's population focus. Many nurse practitioners are excellent clinicians. The point is disclosure: know who is responsible for your care before you sign.

Do I have to leave my current primary care doctor?

No, and most people shouldn't. Keep your insurance-based primary care for acute issues, prescriptions, referrals, and hospital coverage, and add longevity care alongside it. Tell both sides the other exists and ask that records flow between them. Duplicated testing and contradictory advice are the main risks of keeping them in separate silos.

Final Word: Longevity Medicine Is A Relationship, Not A Receipt

San Francisco has real options. A physician-led executive assessment in Union Square. Concierge doctors in the city and on the Peninsula who will pick up the phone. A metabolic medicine practice built around VO2 max and retesting. A board-certified internist practicing functional medicine in San Mateo. Hormone physicians with decades of conventional practice behind them. An integrative program in Mill Valley. A regenerative orthopedist who treats professional dancers. Five years ago, that market didn't exist here.

It also has an expensive theater. From the homepage, the two are indistinguishable.

So use the filters. Pick your lane before your brand. Verify the license against the right California board, not the logo on the wall. Ask who is actually in the room with you. Get Lp(a) measured once, whether you spend $200 or $20,000. Be honest with yourself about what a full-body MRI can and cannot tell a healthy 42-year-old. And judge the whole arrangement on what exists at day 90: a written plan, a number that moved, and a human being who answers.

The sick-care system waits for you to break. The right longevity doctor doesn't. But the right one is a person you'll still be working with in 2030, not a report you'll read twice and forget.

Start with the ten-minute license check tonight. Everything else follows from knowing who you're actually hiring.

Medical Disclaimer And About The Author

I'm not a doctor. I don't pretend to be one.

I've been helping people with their health since 2006, and the last ten years of that have been longevity specifically. I hold a certification in nutrition from the Institute for Integrative Nutrition (IIN), and I've been a lifelong learner and athlete. I track my own biomarkers, wear a CGM periodically, test my VO2 max and body composition, and ride long gravel races. That makes me an informed participant and a careful reporter on this market, not a clinician. Where this page describes what evidence supports, it is summarizing published guidelines and peer-reviewed research, each linked at the claim.
