Personalized Functional Medicine in Boston
A More Personal Approach to Functional Medicine in Boston
Here, your health is understood as a whole — and healing is designed around you.
At its core, functional medicine is a personalized, root-cause approach that looks beyond symptoms to identify underlying imbalances. It is not a replacement for traditional medicine, but an extension of it: offering a deeper, more integrative way to understand and support your health.
By examining how systems like gut health, hormones, metabolism, mitochondrial health, and immune function work together, we’re able to uncover what’s happening beneath the surface and create a clear path toward lasting wellness.
Through advanced testing, personalized nutrition, and targeted lifestyle support, I help you move beyond symptom management and toward true, sustainable healing.
YOUR BOSTON FUNCTIONAL MEDICINE PRACTITIONERMeet Isabel Walls,
PA-C, IFMCP-M
I am a Board Certified Physician Assistant and Certified Functional Medicine provider with more than 15 years of experience in primary care, family medicine, and integrative health. I completed my undergraduate studies at Vanderbilt University, pursued my pre-medical post-baccalaureate training and certification through Georgetown University, and earned my Master of Science in Physician Assistant Studies from Massachusetts College of Pharmacy and Health Sciences.
My work has evolved into a more holistic, root-cause approach to medicine, supported by advanced training through the Institute for Functional Medicine (IFM) and the School of Applied Functional Medicine (SAFM). I focus on digestive health, autoimmune conditions, hormone and thyroid balance, metabolic health, and integrative approaches to mental health and fertility, often incorporating a “food as medicine” philosophy alongside advanced testing and personalized care.
Outside of practicing medicine, you’ll find me spending time with my family, in a vinyasa flow, and exploring New England trails with my rescue, Cunucu.
“I am so thankful for how she's enabled me to feel healthy.
When I met Isabel, my health was in a precarious and difficult place, with COVID, Hashimoto's thyroid disease, and chronic colitis. I struggled to really find a central medical professional who saw my health and conditions holistically to partner with on a condition and treatment basis.
Now, nearly 4 years later, we are still working together, and while my health has continued to navigate many turns and shifts, Isabel's guidance, advice, and partnership have been paramount in my ability to improve. I cannot imagine the past four years without her support.”
