What is Longevity Medical Center?
Longevity Medical Center is a physician-run practice led by Hans Gruenn MD, with offices in Los Angeles at 12301 Wilshire Blvd. and in Ojai. It is built around functional and integrative medicine, with therapies listed for brain health, longevity medicine, medical weight balancing, intermittent fasting, hormone replacement for both men and women, and heavy metal detox. This is not a single-service weight loss shop. Weight management is one offering inside a broader practice that treats hormone decline and aging as connected issues.
For weight loss, the practice names Ozempic and Mounjaro as GLP-1 options, but frames them as part of a larger program addressing metabolism, thyroid and adrenal function, and sleep rather than a prescription handed over on its own. For testosterone therapy in men, it describes treatment by weekly intramuscular injections or daily skin applications, alongside lab testing that includes PSA and adrenal hormone levels. For women, it discusses bio-identical hormone options and hormone testing through blood, urine, or saliva. Dr. Gruenn only sees patients who live in California, so this is not an option for people out of state looking for telehealth.
What does it cost?
No prices are published for any program, consultation, or lab work. It does not say whether a monthly fee, if there is one, includes the cost of medication. If you call, ask for a specific number before you commit to anything.
What is published is the cancellation policy: a 2-business-day notice is required, and missing that window means a charge of 50% of the service fee. The practice also states plainly that it does not accept any insurance, so this is cash pay only, and you should ask directly whether HSA or FSA funds can be used.
What should you ask before you book?
Ask whether Dr. Gruenn is the one who writes your prescription and sees you at each visit, since he is the only prescriber named. Ask whether the weight loss medications are brand-name (Ozempic, Mounjaro) or compounded versions, and whether the monthly cost includes the medication itself or just the visit. Ask what the lab work costs, since testosterone and hormone therapy both involve blood panels before and after starting treatment. Ask whether any visits can be done by telehealth or whether every appointment requires an in-person visit to Los Angeles or Ojai. Ask what counts as canceling in time, given the 2-business-day policy and the 50% charge for missing it.
Who is it a good fit for?
This is a good fit if you live in California, want a physician overseeing hormone or weight therapy as part of a broader functional medicine approach rather than a single injection protocol, and you are comfortable paying cash while you sort out exact costs by phone. It is probably not a fit if you want transparent published pricing up front or need care delivered entirely by telehealth from outside the state.
