About My Path Functional Medicine
What is My Path Functional Medicine?
My Path Functional Medicine is a functional medicine practice in Brookline, Massachusetts, at 1330 Beacon St, run by Dr. Katherine Lantsman, MD, a board certified internist who founded the practice in 2012. The core of the practice is functional and integrative medicine: long diagnostic visits, lab-heavy workups, and an approach aimed at finding an underlying cause rather than just managing symptoms. Within that, it offers a weight loss program and hormone therapies, including treatment for low testosterone, perimenopause and thyroid dysfunction, along with fertility wellness, food allergy testing, parasite testing, IV glutathione and other functional medicine services.
For hormone treatment, the practice says it works with compounding pharmacies to customize treatment for each patient, rather than prescribing standard commercial formulations. The weight loss program is described as starting with an investigation into why a patient has gained weight and why past efforts have not worked, rather than naming a specific medication protocol. Appointments are available both in the office and by telemedicine.
What does it cost?
The practice does not accept insurance and is self-pay. Appointments are billed at $540 an hour, and an initial visit is typically around two hours, for $1,080. Brief email or portal messages to Dr. Lantsman cost $50, and paperwork requests like letters or forms are $25, with more involved paperwork billed at the hourly rate. A lab test kit runs $10 for ordering and handling, a glutathione IV push is $75 for one gram or $95 for two grams, and a standard blood draw is $25 ($45 for the Genova Diagnostics NutrEval test). Separate lab panels are listed too, for example a NutrEval at $439 or a GI-MAP at $399, billed directly to the lab rather than through the office. None of these published prices are specific to the weight loss program or hormone therapy, and no medication cost is listed, so what a weight loss or hormone treatment plan runs month to month is not stated.
What should you ask before you book?
Ask whether the $540 hourly rate is expected to cover the full course of a weight loss or hormone program, or whether medication is billed separately through a compounding pharmacy. Ask what the compounded medication itself costs, since the practice does not name specific drugs or doses for weight loss or hormone treatment. Ask how follow-up visits are typically billed, since they vary in length, and what a realistic first-year cost looks like once labs, blood draws and electronic messaging fees are added up.
Who is it a good fit for?
This is a good fit for someone drawn to a slower, lab-driven workup under one physician, who is comfortable paying hourly rather than a flat program fee and wants to ask line by line what a weight loss or hormone plan will add up to before starting.
