Best Longevity Doctors in Los Angeles: Top 7 Physicians Compared

Los Angeles is a fantastic place to find longevity care and a terrible place to choose it casually. You can find real physician-led, testing-heavy prevention work here. You can also find a lot of “optimization” branding that turns out to be an expensive waiting room plus a supplement cart.

That’s why this page sorts clinics by patient goal, not by who has the glossiest website. Before you book, it also helps to understand what separates a real longevity clinic from a prettier version of concierge care.

If you want that bigger-picture context, read Longevity Clinics Explained and Personalized Longevity Care: What Medicine 3.0 Really Means.

Key Takeaways

1. Dr. Allan Kurtz at California Center of Longevity & Functional Medicine is the strongest fit for preventive cardiometabolic workups, executive-style screening, and patients who want heart-risk testing baked into the conversation early.
2. Dr. Hans D. Gruenn at Longevity Medical Center is the best under-the-radar pick for broad functional medicine, hormone evaluation, gut workups, and a clearly spelled-out new-patient testing process.
3. Dr. Rashel J. Tahzib at Advance Health Integrative & Functional Medicine is the clearest choice for people who want a structured functional-medicine intake, targeted labs, and follow-up built around hormones, thyroid, gut health, and lifestyle repair.
4. Dr. Rachel West at Dr. Rachel West Integrative Medicine is the best fit for patients who want a longtime integrative physician with a wide diagnostic menu, women’s health experience, and old-school integrative branding rather than biohacker marketing.
5. Dr. Arash Bereliani at Beverly Hills Institute for Cardiology & Preventive Medicine is the strongest fit for people with "normal" labs and a family history who want genetic and advanced-lipid testing, plus the option to move into concierge-level care.
6. Dr. Ilan Kedan at Cardiolucent is the clearest choice for a solo, cardiologist-run annual risk assessment with same-day imaging, ApoB and Lp(a) testing, and a written 12-month plan.
7. Dr. William Pittman at Concierge Health LA is the best fit for people who want one concierge internist coordinating primary care, specialists, and prevention, with 24/7 access and a dedicated care coordinator.

How I Chose These Clinics

These clinics made the cut because they had a clearly identified lead clinician, a visible clinical lane, meaningful diagnostics on the public site, and some sign that care continues after the intake instead of dying the second your credit card clears.

I also leaned toward clinics with clinical depth over marketing polish. That matters. Big review numbers and slick branding are not the same thing as thoughtful prevention care.

This list is for people trying to make a good first call, not for people shopping for the loudest ad budget.

What Is a Longevity Doctor?

A longevity doctor is a clinician who tries to reduce future disease risk before the disease becomes obvious. In the serious version of the field, that means prevention, biomarkers, targeted diagnostics, and follow-up over time.

The science anchor here is geroscience: aging biology is deeply tied to chronic disease risk, and the goal is to translate that biology into better interventions earlier, not just prettier lab reports.

The National Institute on Aging frames geroscience as research into the biological mechanisms that drive aging and the conditions that come with it.

A standard primary care visit is often built to solve the problem in front of you. A longevity practice is trying to solve the next decade.

That can be smart. It can also get stupid fast when clinics act like every peptide, IV, and detox story carries the same level of evidence. It does not.

In California, you’ll see both MD/DO physicians and naturopathic doctors in this space. California does license naturopathic doctors, but their scope is governed by statute and regulation, so don’t treat “doctor” as a personality trait. Read the credential line carefully.

A real adult move, I know. For background, see the National Institute on Aging’s geroscience overview and the California Board of Naturopathic Medicine scope statement.

Longevity Doctor vs. Functional Medicine Doctor vs. Concierge Doctor

A longevity doctor is defined by the goal: to prevent disease earlier, track the right biomarkers, and help you stay capable for longer.

A functional medicine doctor is defined more by the method: root-cause work across hormones, gut health, nutrition, inflammation, and lifestyle.

The access model defines a concierge doctor: more time, easier communication, and membership-style care, whether or not the clinical philosophy is truly longevity-focused.

In real life, these categories overlap. A doctor can be longevity-focused and functional-medicine trained. A clinic can be concierge without doing especially deep prevention work.

That’s why the better question is not which label sounds smartest. It’s which model matches your goal, your budget, and the amount of follow-up you actually want.

Why Los Angeles Is Becoming a Longevity Medicine Hub

Los Angeles has the perfect recipe for a booming longevity market: money, status anxiety, outdoor culture, performance obsession, and a huge population base.

LA County is the largest county in the nation by population, with nearly 10 million residents, which means the market is big enough to support every flavor of prevention care from old-school integrative medicine to genomics-heavy concierge practices.

But LA is not just celebrity wellness cosplay. USC’s Longevity Institute calls itself one of the leading institutes for translational research on aging and age-related disease, with work spanning dietary, pharmacologic, regenerative, and engineering approaches to healthspan.

That matters because it gives the city real aging-science gravity, not just cold-plunge content. You can browse the USC Longevity Institute if you want the academic backdrop.

The city also rewards niche clinics. A patient population this large creates room for highly specific lanes: executive prevention, hormone optimization, women’s midlife care, gut-first functional medicine, preventive cardiology, and concierge primary care.

The upside is choice. The downside is that “longevity” now covers everything from excellent preventive medicine to wellness theater with a stethoscope.

That’s the real LA angle. The city didn’t invent longevity medicine. It just gave it better lighting and a much bigger customer base. Your job is filtering for clinical substance before the branding gets there first.

What to Look for in a Longevity Doctor in Los Angeles

You do not start with branding. You start with clinical clarity.

First, identify the lead doctor before you book. If the website makes it weirdly hard to tell who is actually directing care, that’s a problem. “Our team” is not a treatment plan.

You should know whether you’re booking with an MD, DO, ND, or a rotating cast of people with very good lighting.

Second, look for diagnostic depth. That does not mean the longest menu. It means the right tests for the right reason.

Good clinics explain whether they use conventional labs, specialty testing, genomic work, cardiometabolic screening, hormone panels, stool testing, or other targeted diagnostics.

Bad clinics hide behind vague words like “customized” and hope you stop asking questions.

Third, look for continuity. The intake matters. The follow-up matters more. A serious longevity clinic should make it obvious what happens after testing: who reviews results, how the plan changes, how often you’re seen again, and what “success” actually looks like.

If the whole thing feels like a spa package with lab requisitions, keep moving.

A lot of anti-aging clinics are basically hormone menus with better branding. Real longevity care is broader than that. It should help you understand risk, not just chase vibes.

Do This Now: Before you book, write down your main goal in one sentence: “heart-risk prevention,” “midlife hormones,” “fatigue and metabolic repair,” or “a concierge doctor who coordinates everything.”

If you can’t name the goal, you’ll get sold the clinic’s favorite package instead of the care you actually need.

Dr. Allan Kurtz, D.O.

If your version of longevity starts with risk prevention, not vibes, Kurtz is an easy doctor to take seriously. His lane is less “biohacking spectacle” and more cardiometabolic screening, executive-style prevention, and figuring out where the real trouble is before it gets expensive. His site does list stem cell and PRP therapy, but prevention is clearly the center of the practice.

California Center of Longevity & Functional Medicine

1. Clinic: California Center of Longevity & Functional Medicine
2. Address: 6325 Topanga Canyon Blvd., Suite 501, Woodland Hills, CA 91367
3. Website: https://www.californiacenteroflongevitymedicine.com/
4. Specialties: Cardio-metabolic health, gastrointestinal health, hormone optimization, laboratory assessments, IV nutrition therapy, executive physicals, heart-disease inflammation testing
5. Best for: People who want an old-school internist with a prevention-first bent, especially around cardiometabolic risk and executive-style screening
6. Pricing context: Pricing shared during consultation. Data as of October 2026.
7. Location cue: Woodland Hills / western San Fernando Valley
8. Care model: Private physician-led prevention practice focused on executive-style screening, lab assessment, and functional/integrative medicine.

What the first 30-90 days look like:

His Ultimate Executive-CEO Physical includes advanced lipid and thyroid testing, coronary calcium scoring, carotid and aortic ultrasound, bone density, hormone and cortisol testing, food allergy and vitamin testing, and inflammation testing through his in-house Heart Attack and Stroke Prevention Center. It also includes a nutritional assessment with an integrative dietitian. Follow-up is with Dr. Kurtz or through a specialist referral.

Kurtz is the best fit on this page for people who think like operators. If your brain goes straight to “Show me the cardiovascular risk, the inflammation picture, the lab data, and then let’s talk strategy,” he makes immediate sense.

His site is dated, which honestly works in his favor here. It reads like a doctor’s site, not a growth-marketing funnel.

That means you get less polish and more direct clues about what he actually cares about: cardiometabolic risk, executive physicals, lab assessments, hormones, GI issues, and prevention before things go sideways.

If you’re looking for flash, this is not your guy. If you want a clinic that still sounds like medicine when it talks about longevity, he may be your first call.

I’d especially look here if your priorities are heart health, diabetes risk, inflammation, or the kind of broad preventive exam high-functioning professionals usually postpone until something finally scares them.

Kurtz is the internist’s take on heart-risk prevention, folding in hormones, GI and nutrition. If you want a cardiologist running the numbers, Bereliani and Kedan are the more specialized calls.

Dr. Hans D. Gruenn, MD

Gruenn is a strong fit for the person who knows something is off but is tired of being told everything looks “basically normal.”

His practice leans into broad functional workups, hormones, gut issues, and the kind of step-by-step follow-up that too many clinics conveniently overlook.

Longevity Medical Center

1. Clinic: Longevity Medical Center
2. Address: 12301 Wilshire Blvd., Suite 315, Los Angeles, CA 90025
3. Website: https://www.drgruenn.com/
4. Specialties: Functional and conventional lab workups, hormone deficiency evaluation, gut health, nutritional deficiencies, adrenal health, heavy metal toxicity, immune issues, longevity medicine
5. Best for: People who want a broad functional-medicine workup with a clearly stated intake and planning process
6. Pricing context: Pricing shared during consultation. Data as of October 2026. The clinic states it does not accept insurance and provides a superbill.
7. Location cue: Wilshire Boulevard office in Los Angeles, zip code 90025. He also has an Ojai office and sees California residents only.
8. Care model: Cash-pay consultative practice with a structured medical workup, a therapy-planning visit, and follow-up once labs are back.

What the first 30-90 days look like:

This is one of the few clinics here that explains the sequence publicly. New patients get a medical history, physical exam, and conventional plus functional lab testing.

Once results are in, the office calls to set up a therapy-planning visit, where Dr. Gruenn reviews the findings and builds a personalized treatment plan. He calls patients himself only if a result is critical.

Gruenn’s big advantage is clarity. He tells you, in plain language, what he may evaluate when indicated: allergies, nutritional deficiencies, adrenal and hormone health, gut health, viral and immune issues, neurotransmitters, heavy metals, genetic vulnerabilities, body composition, and mitochondrial function.

That doesn’t automatically make every lane equally evidence-strong, but it does tell you he’s thinking in systems, not just selling a single protocol.

He also gets credit for publishing a real “results and planning” step instead of pretending the intake alone is the service. That matters. A lot of clinics are happy to talk about functional testing and much less happy to explain what happens after the PDF lands in your inbox.

If you’re dealing with fatigue, hormone questions, gut issues, or the general sense that “something is off, but no one has mapped the whole picture,” this is a strong under-the-radar option.

He is less optimized for social media than for actual pattern recognition, which is not the worst trade in Los Angeles.

Dr. Rashel J. Tahzib, AOBFP, IFMCP

Tahzib makes sense for patients who want a more structured functional-medicine process instead of a generic optimization pitch.

If your issues live somewhere between fatigue, hormones, thyroid, gut dysfunction, and chronic “I don’t feel right,” her model is one of the clearest on this list.

Advance Health Integrative & Functional Medicine

1. Clinic: Advance Health Integrative & Functional Medicine
2. Address: 1849 Sawtelle Blvd., Suite 610, Los Angeles, CA 90025
3. Website: https://drrashel.com/
4. Specialties: Functional medicine, integrative medicine, anti-aging medicine, targeted lab testing, thyroid optimization, bio-identical hormones, gut and toxicity evaluation, lifestyle and stress management
5. Best for: People with fatigue, thyroid or hormone issues, gut complaints, and chronic symptoms who want a structured functional-medicine process
6. Pricing context: Public pricing is listed for some services. Customized Functional Wellness Assessment: $375-$525. Functional Medicine Consultation: $385-$695. The Customized Functional Wellness Assessment is a wellness consult in which pharmaceutical medications can’t be ordered, with 25, 40, or 60-minute options. Data as of October 2026.
7. Location cue: West Los Angeles / Sawtelle. She also runs a mobile and virtual practice serving Greater LA and Denver, with a second office in Greenwood Village, Colorado.
8. Care model: Consultant-style functional medicine practice that works alongside your primary care doctor and follows a defined intake-to-follow-up sequence.

What the first 30-90 days look like:

Tahzib’s site is unusually specific. Patients start with an online health assessment and a complimentary phone discussion, then book an initial consultation.

In that visit, she reviews medical history and recommends targeted lab work; after labs are complete, she uses the initial follow-up visit to explain results and create an individualized program.

The site also says most chronic-condition patients can expect the new-patient visit, an initial follow-up, and roughly four follow-up visits over a year. Once stable, most patients return about twice a year.

This is the most clearly structured functional-medicine clinic in the group. If your brain likes sequence, expectations, and an actual map, Tahzib gives you one.

Her public materials repeatedly circle the same lane: systems biology, root-cause work, thyroid and hormone balance, gut health, targeted testing, and ongoing recalibration.

I also like the honesty of one buried but important line on her site: she practices as a consultant in functional medicine and requires patients to maintain a primary care physician.

That is not sexy marketing. It is a useful boundary. It tells you this clinic is positioning itself as specialized longitudinal support, not pretending it replaces everything else.

If your main complaint is “I’ve been told all my labs are normal and I still feel terrible,” this is one of the strongest fits in LA. Just make sure you actually want a functional-medicine relationship, not a quick optimization package and a cute PDF.

Dr. Rachel West, D.O.

West is the pick for folks who want an experienced integrative physician without the startup-wellness aesthetic.

Her practice feels broader, more clinical, and especially relevant for women’s health, longer-running chronic issues, and patients who want someone to look at the full picture.

Dr. Rachel West Integrative Medicine

1. Clinic: Dr. Rachel West Integrative Medicine
2. Address: 12300 Wilshire Blvd., Suite 420, Los Angeles, CA 90025
3. Website: https://drrachelwest.com/
4. Specialties: Integrative family medicine, women’s health, chronic disease, chronic pain, hormonal balancing, nutritional testing, comprehensive cholesterol testing, advanced urine testing, hormone replacement, osteopathy
5. Best for: Women in midlife and patients who want broad integrative medicine from a physician who is not trying to cosplay as a startup
6. Pricing context: The new-patient packet lists a new-patient consultation (about 45 minutes) at $900, a new-patient consultation for cancer or autism (about 60 minutes) at $1,100, a follow-up (about 30 minutes) at $400, and a $75 blood draw fee. The office is out of network for PPO plans. Data as of October 2026.
7. Location cue: Wilshire Boulevard office in Los Angeles, zip code 90025
8. Care model: Physician-supervised integrative family medicine practice with new-patient forms, follow-up forms, and a broad diagnostic menu. New patients may be seen by other practitioners working under Dr. West’s medical supervision.

What the first 30-90 days look like:

New patients fill out intake forms online, or print them and bring them to the first appointment, then call the office to book. When you call, ask whether your first visit will be with Dr. West herself or another practitioner on her team.

The practice also publishes a follow-up form and notes that it works with multiple specialty and standard labs, including Quest, Labcorp, Genova, and Doctors Data.

Her office policy says Dr. West generally doesn’t communicate with patients between scheduled visits. Messages go to her team by email or text, and questions that need a medical decision require an office visit or a phone consultation. Phone follow-ups are billed like office visits, so budget for that if you expect to check in often. Beyond that, care model details are shared during consultation.

West is not the most stereotypically “longevity” doctor on this list, and that’s exactly why some readers will prefer her.

Her practice reads more like established integrative medicine than modern biohacker branding: women’s health, chronic disease, nutritional testing, osteopathy, hormones, and a wide spread of diagnostic and therapeutic tools.

That comes with a tradeoff. Her treatment menu is broad, and more alternative than the branding suggests. It includes chelation, ozone-based therapies, ultraviolet blood irradiation, IVIG, hyperbaric oxygen, SOT, and homeopathy. Ask which therapies would apply to your plan, why, and what she would prioritize first.

Broad can mean flexible. It can also mean diffuse. A good first call here is for someone who wants an experienced physician to think across hormones, chronic symptoms, and integrative testing, especially around women’s health and longer-running issues that don’t fit neatly into one specialty box.

If I were a woman in perimenopause or menopause who also had chronic fatigue, autoimmune noise, or digestive issues in the mix, this is one of the more interesting calls on the board.

Dr. Arash Bereliani, MD, FACC

Bereliani is the pick for people whose cholesterol panel came back "fine" and who still don't trust it. He's a cardiologist who builds prevention around genetic risk, advanced lipid testing, and early arterial changes, then layers concierge access on top for patients who want it.

Beverly Hills Institute for Cardiology & Preventive Medicine

1. Clinic: Beverly Hills Institute for Cardiology & Preventive Medicine
2. Address: 125 North Robertson Boulevard, Beverly Hills, CA 90211 (second office: 50 North La Cienega Blvd., Suite 150, Beverly Hills, CA 90211)
3. Website: https://www.berelianimd.com/
4. Specialties: Preventive cardiology, genetic risk testing (including APOE), cholesterol particle testing, arterial stiffness screening, cardiovascular testing and monitoring, in-office ultrasound, health optimization, functional and orthomolecular medicine
5. Best for: People with a family history of heart disease, "normal" labs and lingering worry, or a cardiologist-led prevention plan they want to upgrade to concierge-level access
6. Pricing context: Pricing shared during consultation. Membership tiers are described publicly, but fees are not listed. Data as of October 2026.
7. Location cue: Beverly Hills, Robertson Boulevard and La Cienega medical corridor
8. Care model: Physician-led cardiology and internal medicine practice with optional tiered concierge membership (Elite, Enhanced, Premier).

What the first 30-90 days look like:

The site describes a full medical history, a thorough physical exam, and diagnostic testing for genetic and biomarker risk factors. Named screenings include a finger-clip arterial stiffness test (MaxPulse), APOE genetic testing, and LDL particle size and count.

From that workup, he builds an individualized prevention plan and can bring in a dietitian, fitness trainer, psychotherapist, and hypnotherapist. Follow-up frequency isn't published for standard patients. The Enhanced tier adds a personal medical liaison, extra office visits, and double the testing. The Premier tier is capped at 20 patients, by invitation only, and currently has a waitlist.

Bereliani is the closest thing on this list to precision prevention with a cardiologist's spine. His core argument is one a lot of patients need to hear: a normal cholesterol panel and a passed treadmill test do not mean you're safe. So he goes looking for what those tests miss.

His credentials hold up. He's board-certified in cardiovascular disease and internal medicine, trained at UCLA, has taught at UCLA's medical school since 2003, and is on staff at Cedars-Sinai.

The tiered membership is what sets him apart. You can start as a regular cardiology patient and move into a higher-touch relationship later, instead of committing to a large program on day one.

The honest caveat: his site leans on functional and orthomolecular medicine and links to his own supplement line. That's not disqualifying, but ask which recommendations come from guideline evidence and which come from the supplement cabinet.

APOE testing deserves its own question too. It carries Alzheimer's risk information, not just heart risk, so ask how results are explained before you agree to it.

If your version of longevity starts with "am I going to have a heart attack I didn't see coming," Bereliani is one of the most specific answers in LA.

Dr. Ilan Kedan, MD, MPH

Kedan is the pick for people who want one cardiologist to own their heart-risk picture year after year, with the numbers written down. His practice is small on purpose, and it's one of the few on this list that publishes exactly what a prevention visit includes.

Cardiolucent

1. Clinic: Cardiolucent
2. Address: 99 La Cienega Blvd. #303, Beverly Hills, CA 90211
3. Website: https://www.cardiolucent.com/
4. Specialties: Concierge and preventive cardiology, advanced lipid management (ApoB, Lp(a)), metabolic health assessment, longevity assessment and plan, executive physicals, VO2 max testing, in-office echocardiography, point-of-care ultrasound (POCUS), carotid and abdominal ultrasound, exercise stress testing
5. Best for: Data-minded adults in their 40s and up, people with a family history of early heart disease, and anyone who wants a cardiology baseline with a written annual plan
6. Pricing context: Pricing shared during consultation. Data as of October 2026. The practice does not accept Medicare or insurance and provides a superbill for out-of-network reimbursement. It takes HSA/FSA, and the consultation fee is credited toward membership if you enroll.
7. Location cue: Beverly Hills, La Cienega Boulevard near the Cedars-Sinai corridor
8. Care model: Solo concierge cardiology practice with a deliberately small patient roster. Plans range from office and hospital visit packages to an unlimited concierge plan with at-home visits.

What the first 30-90 days look like:

The site lays out the annual risk assessment clearly. It starts with a 60-plus-minute consultation and same-day echocardiogram, EKG, and POCUS in the office. It also includes an advanced lipid and metabolic panel, a numerical 5- to 10-year risk score, and coronary calcium scoring when your risk warrants it.

Most of that workup happens in a single block rather than spread over several visits. You leave with a written plan covering lipid and blood pressure targets, medication strategy, exercise and nutrition priorities, and when to retest. Between annual visits, you reach Dr. Kedan directly. Higher-risk patients get interim visits on a schedule he sets in the plan.

Kedan is the most transparent cardiology option on this list. Most clinics say "advanced testing." His site tells you which markers, which imaging, how long the visit runs, and what you walk out with.

The resume is serious. He's board-certified in internal medicine, cardiovascular disease, and echocardiography. He trained at Tulane, Washington University, and Georgetown, and earned an MPH from Columbia. Before opening Cardiolucent, he practiced at Cedars-Sinai Medical Group and cared for more than 15,000 patients.

He has also performed more than 45,000 point-of-care ultrasound exams. That matters because it means imaging happens in the room with the doctor who interprets it, not three weeks later at a different building.

He also says he handles every visit himself and never hands patients off to a mid-level provider. In a city where "physician-led" often means "physician-adjacent," that's worth noting.

The honest caveat: this is a cardiology lens, not a whole-body longevity program. He positions the annual assessment as the cardiology counterpart to your primary care visit, not a replacement. If your priorities are hormones, gut health, or menopause, he's a complement to another clinic on this list, not a substitute.

If you want your heart risk turned into a number, a target, and a date to recheck, Kedan is one of the cleanest calls in LA.

Dr. William Pittman, MD

Pittman is the pick for people who want one doctor quarterbacking everything: primary care, prevention, specialists, and the longevity layer on top. He's less a longevity specialist than a longevity-minded internist with time, access, and a care coordinator.

Concierge Health LA

1. Clinic: Concierge Health LA
2. Address: 8484 Wilshire Blvd. Suite 570, Beverly Hills, CA 90211
3. Website: https://www.conciergehealthla.com/
4. Specialties: Concierge primary care, longevity medicine, hormone optimization, cardiovascular health, lifestyle medicine, peptide therapy, complex care for multiple chronic conditions, medically supervised weight loss, specialist coordination
5. Best for: Busy professionals and families who want a single concierge physician managing prevention and everything else, especially people juggling several chronic conditions or specialists
6. Pricing context: Pricing shared during consultation. Data as of October 2026. Membership pricing is available on request. Home visits cost extra. Members get discounts on partner services, including 20% off supplements through Fullscript.
7. Location cue: Beverly Hills, Wilshire Boulevard near La Cienega
8. Care model: Membership-based concierge primary care with 24/7 direct physician access, same-day appointments, a dedicated care coordinator, and monthly chart reviews.

What the first 30-90 days look like:

Care starts with a consultation, and onboarding details are shared during that consultation. Public materials describe a comprehensive health check covering an in-depth exam, labs, heart health assessment, cancer screening, fitness evaluation, and lifestyle and mental health review.

After that, a dedicated care coordinator schedules your screenings, tests, and specialist visits. The practice also runs monthly chart reviews and can monitor data from wearables like an Apple Watch or Fitbit.

Pittman is the strongest pure concierge model on this list. If your main frustration is chasing referrals and remembering which test is overdue, his setup is built to take that job off your plate.

His background is more substantial than his website lets on. He's board-certified in internal medicine, trained at Cedars-Sinai, and is on staff there. At UCLA Health, he was a senior physician in the complex-care clinic, worked in the lipidology clinic, and served as associate director of the Long COVID program.

That lipid and complex-care experience is exactly what you'd want in a prevention-minded internist. It just isn’t spelled out on his longevity page, which reads generically and doesn’t name specific biomarkers or imaging. He makes this list more about the training and access model than about published testing details.

The honest caveat: before you join, ask what longevity testing actually looks like here. Does he check ApoB, Lp(a), coronary calcium, VO2 max? How often are labs repeated, and what changes the plan? If the answers are specific, you've found a well-trained internist with real access. If they're vague, you're paying for convenience.

For people who want a concierge doctor first and a longevity program second, Pittman is a smart, low-drama first call.

Quick Comparison Table

These matches are based on the clinics’ publicly stated services, diagnostics, and care models.

Do This Now: Pick the row that sounds most like your actual problem. Then call only one or two clinics that match it. Booking five consults because “more options” feels productive is how people burn money and stay confused.

How to Choose the Right One for You

Start with the clinical lane, not the branding. “Longevity” is not a lane. It’s a banner. Your real question is whether you need heart-risk prevention, hormone work, gut-first functional medicine, women’s midlife support, cardiology-led risk testing, or concierge primary care.

Before you book, ask four questions:

1. Who is actually leading my care?
2. What testing do you usually start with for someone like me, and why?
3. What does follow-up look like in the first three months?
4. Do you handle this like primary care, a consultant relationship, or concierge medicine?

Those four questions cut through almost all the nonsense. If the answers are vague, evasive, or weirdly salesy, move on.

The right doctor is the one whose clinical lane matches your problem and whose follow-up model matches your reality.

Not the one with the best lighting. Not the one with the longest peptide menu. Not the one whose receptionist says “optimization” like it’s a diagnosis.

Do This Now: Write your goal, your budget, and your tolerance for ongoing care on one page. Then book the clinic that fits all three. That one move will save you more time than reading twenty more “best doctor” lists.

Frequently Asked Questions

What does a longevity doctor actually do?

A longevity doctor focuses on prevention, biomarkers, and follow-up care to reduce future disease risk before disease becomes apparent. The serious version is less about hype and more about structured risk assessment, testing, and long-term monitoring.

Are longevity doctors real medical doctors?

Some are MDs or DOs, and some clinics in this broader market may be led by licensed naturopathic doctors, depending on state law. In Los Angeles, the safest move is to read the credential line first and verify who is directing care.

Which Los Angeles longevity doctor is best for hormone optimization?

For classic hormone-plus-metabolic repair, Dr. Rashel Tahzib and Dr. Hans Gruenn are strong fits. For women’s midlife issues wrapped inside broader integrative care, Dr. Rachel West is the more natural call. If you’d rather have hormone care handled inside a concierge primary care relationship, Dr. William Pittman offers hormone optimization as part of his practice.

Do longevity doctors in Los Angeles take insurance?

Many do not. Gruenn states the clinic does not accept insurance and provides a superbill. Kedan’s Cardiolucent does not accept Medicare or insurance, provides a superbill, and notes that imaging and labs ordered outside the office often go through your regular insurance. West’s office materials describe out-of-network reimbursement limits. Ask the clinic directly before assuming anything.

How much does a longevity doctor cost in Los Angeles?

Public pricing on this shortlist runs from $375 to $695 for Dr. Rashel Tahzib’s consultations, up to $900 for a new-patient consultation with Dr. Rachel West ($1,100 for cancer or autism cases). Tahzib’s lower-priced assessment is a non-prescribing wellness consult. The rest share pricing during consultation, and Cardiolucent credits its consultation fee toward membership if you enroll. Before comparing numbers, ask whether you’re looking at a single consult, a diagnostic workup, or an ongoing membership.

What should a real longevity clinic test first?

That depends on your goal, but a real clinic should be able to explain why it is ordering cardiometabolic, hormone, GI, nutritional, genomic, or specialty testing for you specifically. If the answer is “we test everything,” that’s not sophistication. That’s menu engineering.

Is longevity medicine just anti-aging marketing?

Sometimes, yes. The credible part is preventive medicine, biomarker tracking, and longitudinal follow-up. The shaky part is when clinics market every intervention as equally proven. That’s why you should judge the doctor’s reasoning and care model, not the slogan.

Which Los Angeles longevity doctor is best for women in midlife?

Rachel West is the most natural fit if you want women’s health inside a broader integrative practice. Hans Gruenn and Rashel Tahzib also publish hormone-focused services, but West’s site leans most clearly into women’s health as an ongoing lane rather than a side offering.

Final Thoughts

Los Angeles gives you access to some genuinely interesting longevity doctors. It also gives you enough branding noise to make a smart person do something dumb.

The sick-care system waits for you to break. A good longevity doctor shouldn’t. But that doesn’t mean you hand over your judgment the second someone says “precision,” “bioidentical,” or “root cause.” You want a doctor with a lane, a testing strategy, and a follow-up model that survives the intake.

Pick the clinic that matches your goal. Ask sharper questions than the average patient. And do not confuse an expensive wellness aesthetic with medical clarity. LA does that enough already.

About This Guide and Medical Disclaimer

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 completed the Institute for Integrative Nutrition's health coach training program. That's a coaching certificate, not a clinical degree or a license to practice, and I'm a lifelong learner and athlete who tracks his own biomarkers and rides long gravel races. That's the extent of it. I'm a well-informed consumer of this kind of care, not a licensed clinician.

These articles are for informational purposes only. Nothing here is medical advice, diagnosis, or treatment, and nothing here establishes a doctor-patient relationship. No clinic or physician named in this guide paid for inclusion, and we earn no commission from any of them.

Do not start, stop, or change any medication, supplement, hormone therapy, or exercise program based on something you read here. Talk to a licensed physician who knows your history first, particularly before pursuing hormone therapy, off-label prescriptions like rapamycin, GLP-1 medications, or any regenerative treatment.

Clinic details, services, and pricing change frequently. Everything above reflects publicly available information and should be verified directly with each clinic before you make a decision.

If you're experiencing chest pain, shortness of breath, or any acute symptom, call 911 or go to an emergency department. Don't book a longevity consult.
