Longevity Doctors in Los Angeles, CA: Top Clinics by Goal

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

• 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.
• 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.
• 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.
• Dr. Rachel West at Integrative Family Practice is the best fit for patients who want a long-time integrative physician with a wide diagnostic menu, women’s health experience, and a less biohacker-coded, more old-school integrative style.
• Dr. Mimansa Geere at Mimansa Longevity stands out for concierge precision medicine, genomics-led planning, and people who want a longer, more expensive, high-touch longevity program rather than a one-off consult.

How We 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 intake rather than dying the second your credit card clears.

I also leaned toward clinics with real medical depth but imperfect digital packaging. 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 seeks to reduce future disease risk before disease becomes apparent. 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.

A concierge doctor is defined by the access model: 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, and concierge genomics.

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 “precision genomics.”

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.

California Center of Longevity & Functional Medicine

• Clinic: California Center of Longevity & Functional Medicine
• Address: 6325 Topanga Canyon Blvd., Suite 501, Woodland Hills, CA 91367
• Website: https://www.californiacenteroflongevitymedicine.com/
• Specialties: Cardio-metabolic health, gastrointestinal health, hormone optimization, laboratory assessments, IV nutrition therapy, executive physicals, heart-disease inflammation testing
• Best for: People who want an old-school internist with a prevention-first bent, especially around cardiometabolic risk and executive-style screening
• Pricing context: Pricing shared during consultation. Data as of April 2026.
• Location cue: Woodland Hills / western San Fernando Valley
• 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:
Care model details are shared during consultation. Public materials emphasize the clinic’s Ultimate Executive-CEO Physical, heart-disease inflammation testing through the Heart Attack and Stroke Prevention Center of Southern California, and lab-based evaluation spanning cardiometabolic, hormone, GI, and nutritional status.

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.

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

• Clinic: Longevity Medical Center
• Address: 12301 Wilshire Blvd., Suite 315, Los Angeles, CA 90025
• Website: https://www.drgruenn.com/
• Specialties: Functional and conventional lab workups, hormone deficiency evaluation, gut health, nutritional deficiencies, adrenal health, heavy metal toxicity, immune issues, longevity medicine
• Best for: People who want a broad functional-medicine workup with a clearly stated intake and planning process
• Pricing context: Pricing shared during consultation. Data as of April 2026. The clinic states it does not accept insurance and provides a superbill.
• Location cue: Wilshire Boulevard office in Los Angeles, zip code 90025
• 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 back, Dr. Gruenn schedules a therapy-planning visit to review findings and build a personalized treatment plan; the office then calls patients back when noncritical labs are in, so follow-up can be set.

Gruenn’s big advantage is clarity. He tells you, in plain language, what he looks at first: food and environmental allergies, nutritional deficiencies, adrenal health, hormone deficiencies, gut dysfunction, viral issues, immune deficiencies, neurotransmitters, and heavy metal toxicity.

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

• Clinic: Advance Health Integrative & Functional Medicine
• Address: 1849 Sawtelle Blvd., Suite 610, Los Angeles, CA 90025
• Website: https://drrashel.com/
• Specialties: Functional medicine, integrative medicine, anti-aging medicine, targeted lab testing, thyroid optimization, bio-identical hormones, gut and toxicity evaluation, lifestyle and stress management
• Best for: People with fatigue, thyroid or hormone issues, gut complaints, and chronic symptoms who want a structured functional-medicine process
• Pricing context: Public pricing is listed for some services. Customized Functional Wellness Assessment: $375–$525. Functional Medicine Consultation: $385–$695. Data as of April 2026.
• Location cue: West Los Angeles / Sawtelle
• 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.

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.

Integrative Family Practice

• Clinic: Integrative Family Practice
• Address: 12300 Wilshire Blvd., Suite 420, Los Angeles, CA 90025
• Website: https://drrachelwest.com/
• Specialties: Integrative family medicine, women’s health, chronic disease, chronic pain, hormonal balancing, nutritional testing, comprehensive cholesterol testing, advanced urine testing, hormone replacement, osteopathy
• Best for: Women in midlife and patients who want broad integrative medicine from a physician who is not trying to cosplay as a startup
• Pricing context: Pricing shared during consultation. Data as of April 2026. Public office-policy PDFs show historical fee schedules, but current consultation pricing is not clearly presented on the main site.
• Location cue: Wilshire Boulevard office in Los Angeles, zip code 90025
• Care model: Physician-supervised integrative family medicine practice with new-patient forms, follow-up forms, and a broad diagnostic menu.

What the first 30–90 days look like:
The public site asks new patients to download and complete intake forms before calling for an initial appointment.

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. 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. The site’s treatment menu is broad enough that you should ask sharp questions about what your plan 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. Mimansa Geere, M.D., M.S., IFMCP

Geere is the most precision-medicine-heavy doctor in this group. If you want concierge longevity care built around genomics, deeper personalization, and a high-touch program instead of a one-and-done consult, this is the lane she occupies best.

Mimansa Longevity

• Clinic: Mimansa Longevity
• Address: 2080 Century Park East, Suite 1804, Los Angeles, CA 90067
• Website: https://drmimansa.com/
• Specialties: Precision genomics, longevity medicine, gut health, hormone optimization, metabolic care, functional diagnostics, polygenic risk, and pharmacogenomics interpretation
• Best for: Executives, entrepreneurs, and data-obsessed patients who want concierge precision medicine and can handle concierge pricing
• Pricing context: Public pricing is listed. Silver Tier: $2,888/month or $7,888 paid in full for 3 months. Gold Tier: $3,222/month or $18,888 paid in full for 6 months. Diamond Tier: $3,688/month or $36,888 paid in full for 12 months. Add-on genomic reports: $450 each. Data as of April 2026.
• Location cue: Century Park East / Century City
• Care model: Concierge longevity program model built around tiered memberships, genomics, advanced biomarker testing, and longitudinal guidance.

What the first 30–90 days look like:
The site lays this out clearly. Care starts with either a discovery call or intake, then genomic decoding through the Longevity Blueprint and a personalized precision-longevity assessment.

The 3-month Silver program is positioned as a diagnostic workup and reset; the 6-month Gold program adds monthly physician visits and ongoing email support; the 12-month Diamond program expands into monthly visits, continuous email and text access, and coordination of advanced labs and referrals.

Geere is the cleanest example on this page of a clinic that actually leans into precision longevity as its own lane.

If you care about genomics, SNP interpretation, polygenic risk, pharmacogenomics, sleep/circadian biology, and how those variables intersect with hormones, metabolism, and gut function, this is the most differentiated option here.

It is also the most expensive and the most curated. That is not automatically a problem. It just means this clinic is not pretending to be for everyone.

The people who should call first are the ones who want a high-touch, physician-led, longer-horizon relationship and are willing to pay for depth, continuity, and personalization instead of a one-off consult.

The honest caveat: genomics can be genuinely useful when it changes decisions. It becomes expensive wallpaper when it doesn’t. If you call this clinic, ask exactly how the genomic findings will change testing, treatment, and follow-up in month one, not just in theory.

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, or concierge genomics.

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.

Alternatives We Did Not Include

A few Los Angeles clinics were worth reviewing, but they did not make the final five because this article was built around a specific kind of shortlist: clinics with a clearly defined longevity lane, enough public detail to compare them fairly, and a care model patients could actually understand before making the first call.

Dr. Anju Mathur, MD - Angel Longevity Medical Center

Angel Longevity has a real physician-led, broad functional-medicine offering, and a clear focus on hormone care, menopause support, chronic illness, and testing.

I left it out because the clinic reads more like a broad integrative and functional medicine center than a tightly defined longevity practice.

That does not make it weaker care. It just makes it a less precise fit for a city guide built specifically around longevity medicine as a category.

Dr. Mark Ghalili, DO - Regenerative Medicine LA

Regenerative Medicine LA is centered on stem cell therapy, peptide therapy, IV vitamin therapy, ozone therapy, exosome therapy, and a dedicated biohacking longevity program.

I did not include it because the practice sits more naturally in a regenerative medicine and procedure-heavy biohacking lane than in the physician-led preventive longevity lane this article was trying to map. For a reader comparing doctors by goal, it felt like a different category.

Dr. Howard Liebowitz, MD - Liebowitz Longevity Medicine

Liebowitz clearly operates in the longevity space, with public service pages covering bioidentical hormone balancing, ozone therapy, chelation therapy, detoxification, hormone pellets, prolozone, and ultraviolet blood irradiation.

He missed the final five because the public-facing materials are much clearer on what is offered than on how care is sequenced.

For this article, I gave preference to clinics where a reader could better understand the intake, testing logic, and early follow-up structure before booking.

Dr. Halland Chen - The Longevity Doctor

Halland Chen’s site is clearly longevity-focused and describes a three-step process built around health review, biomarker lab testing, and personalized longevity recommendations that can include IV, nutritional, and biohacking therapies.

I left it out because there was not enough public detail to make the clinic as easy to compare, side by side, with the finalists. The concept is clear. The practical clinic-level detail is thinner. For a shortlist article, it made it harder to rank confidently.

Frequently Asked Questions

What does a longevity doctor actually do?

A longevity doctor focuses on prevention, biomarkers, and follow-up care aimed at reducing future disease risk before obvious disease shows up. 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. For genomics-heavy hormone work, Dr. Mimansa Geere is the premium option.

Do longevity doctors in Los Angeles take insurance?

Some do not. Gruenn states the clinic does not accept insurance and provides a superbill, Mimansa states its services are not insurance-based, and 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 ranges from $375 to $695 for some functional-medicine consultations at Dr. Rashel’s clinic to $2,888 to $3,688 per month for Mimansa’s concierge longevity programs. Those numbers are not apples to apples, so ask one question first: are you comparing 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 just “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.
