What is Form & Function?
Form & Function is mainly a medical spa at 60 Goldens Bridge Rd, Suite #3, Katonah, NY 10536. Its phone number is (914) 228-7453. Linda Harkavy, MD, founded the practice, owns it, and serves as its medical director. The clinic describes itself as a longevity institute, but most of its menu is aesthetic work such as fillers, wrinkle relaxers and body contouring, alongside a wellness menu. Among the services a cash-pay patient might consider are medical weight loss, hormone therapy, peptide therapy, IV therapy and genetic testing. Hours are Tuesday to Friday, 10 am to 6 pm, with Saturday by appointment. Google shows a rating of 5 from 9 reviews.
The weight loss program is built around labs, lifestyle and goals, with progress tracked on a platform called Heads Up AI. The only medication the clinic names is semaglutide, a GLP-1 medication. It describes its approach this way: "weight loss medications as clinically indicated." It also says medication is not required to join the program, and that nutrition, exercise guidance and other wellness therapies are used instead.
What does it cost?
The clinic does not publish prices for weight loss, hormone therapy or peptides, and it does not state a consultation fee. It does not say whether medication is part of any price, or whether insurance is accepted. It points to payment plans and lists memberships, but gives no terms for either. Before you book, ask for the cost of the first visit, the monthly cost with and without medication, and any membership terms.
What should you ask before you book?
Ask who signs your prescription. The clinic names Linda Harkavy, MD, as its prescriber and says you will meet one of its providers at consultation, so ask who that will be. Ask whether the medication is brand-name or compounded, and whether the monthly fee covers it. Ask what follow-up visits, check-ins and lab work cost, since none of that is listed. For peptide therapy, ask which peptides are used, where they come from and who prescribes them, because no products or dosing details are listed. Ask whether any visit can be done by telehealth, since that is not stated. Finally, ask whether it takes insurance or HSA funds, and how cancellation works.
Who is it a good fit for?
This is a good fit if you live in or near Katonah, Bedford, Mount Kisco or Chappaqua, want in-person visits, and are ready to pay cash and get the full cost in writing before you commit. It is a weaker fit if you need published prices, insurance billing or telehealth, since none of those are stated.
