What is San Francisco Preventive Medical Group?
San Francisco Preventive Medical Group is an integrative medicine practice at 380 West Portal Avenue in San Francisco, open for more than 30 years. It is primarily a general integrative and naturopathic clinic, not a weight loss or hormone clinic, though its longevity and anti-aging medicine service is what brings it into this directory. That approach was developed by Dr. Paul Lynn, MD, who along with Alison Kalb, MSPAS, PA-C, is listed as a prescriber there. The clinic also lists naturopathic doctors on staff, Dr. Mischa Grieder, ND and Dr. Amina Mohammad, ND, though naturopathic doctors do not prescribe in the way an MD or PA does.
Beyond anti-aging medicine, the practice offers functional medicine, naturopathic medicine, ketamine IV therapy, IV nutrient infusion, low dose antigen immunotherapy, natural detoxification programs, a walk-in wellness program, and diet and nutritional counseling. It does not name any specific weight loss or hormone therapy medications. It does not say whether visits are in person only or whether telehealth is available. Office hours are 8:30 am to 5:00 pm, Monday through Friday.
In its own words: "Through my extensive training and research, I've been able to make some worthwhile contributions to natural medicine during the past twenty years."
What does it cost?
No prices are published for any service, including the anti-aging medicine program, ketamine IV therapy, or IV nutrient infusions. There is no stated consultation fee, no mention of membership or subscription terms, and no statement about financing or HSA use. Anyone interested should ask directly what a first visit costs, what ongoing visits run, and whether any treatment is billed per session or as a package.
What should you ask before you book?
Ask whether Dr. Paul Lynn or Alison Kalb will be the one managing your anti-aging or hormone-related care, since they are the two listed as prescribers there. Ask whether the practice accepts insurance for any part of a visit, since that is not stated, and ask the same question about lab work, since the cost of testing often matters as much as the visit fee. Ask what a program under "The Four Cornerstones of Health" actually includes session by session, since that phrase is used but not broken down into specifics. If you are hoping for telehealth visits, ask directly, since nothing about remote care is mentioned. Finally, ask what cancellation or refund policy applies if you start a program and want to stop.
Who is it a good fit for?
This is a good fit for someone in or near San Francisco who wants a long-standing integrative practice that treats anti-aging and longevity as one piece of a broader naturopathic and functional medicine approach, rather than a single-purpose weight loss or hormone startup. It is less of a fit for someone who wants published pricing up front or a purely telehealth relationship, since neither is stated.
