About Functional Medical Institute

What is Functional Medical Institute?

Functional Medical Institute is a physician-led practice at 6048 S Sheridan Rd in Tulsa, Oklahoma. It cites 20 years of clinical experience. Its prescribers are Dr. Mark Sherwood, a naturopathic physician, and Dr. Michele Sherwood, a Doctor of Osteopathy, Fellow in Osteopathic Internal Medicine, and iFM Certified Practitioner. The practice describes its work as functional medicine. Google lists it as a medical clinic with a 4.7 rating from 215 reviews.

Care is sold through four membership levels: Starter, Peak, Elite and VIP. Starter includes hormone-specific lab testing and bioidentical hormone therapy, given as creams and injections. Peak adds combo DNA testing, biological age testing, a Kingdom Detox protocol and BioCode formulas. Elite and VIP add Glycan Age testing, an annual longevity report with reversal tracking, and more consultations and follow-up visits. The practice also produces a podcast, books and films. In its own words: "Our standard is optimal, not normal."

What does it cost?

It does not publish prices. No consultation fee appears, and no dollar figure is shown for any membership level. What it does publish is the member discount on supplements and peptides: 15% at Starter, 20% at Peak, 25% at Elite and 30% at VIP. It also lists how many follow-up visits and consultations each level includes, but not what they cost.

It does not say whether it accepts insurance, whether the hormone therapy price includes the medication, or how cancellation and financing work. Ask for a figure in writing before you book.

What should you ask before you book?

Ask which physician will sign your prescription, and whether you will see the same one at each visit. Ask whether the hormone therapy price includes the medication, and if it does not, what the medication costs. Ask whether the creams and injections are brand-name products or compounded, and who makes them. Ask whether telehealth is available, since it is not stated.

Ask what each lab panel and DNA test costs, and whether it is covered by your membership or billed separately. Ask whether insurance is accepted, how a membership is cancelled, and whether any cancellation fee applies. The office number is +1 918-748-3640.

Who is it a good fit for?

This is a good fit if you want physician-guided hormone therapy and lab testing in Tulsa, and you are ready to commit before a price is in writing. It may not suit you if you need the full cost, the medication terms and the cancellation rules before you pay. The patient testimonials are individual accounts, not a forecast of what you will get.
