Collin Gill, DC
Functional Medicine, Chiropractor, Mechanicsburg, Richfield
Functional Medicine & Chiropractic | Mechanicsburg · Manheim
Dr. Gill didn’t take a conventional path to functional medicine — he left a future as a professional violinist to pursue it after experiencing its impact firsthand. That kind of personal conviction tends to show up in how a provider practices. For Dr. Gill, it shows up in his willingness to take on the cases most providers won’t: complex chronic illness, tick-borne disease, pediatric disorders, and conditions that have gone undiagnosed for years.

Dr. Gill focuses on the intersection of immune dysfunction, chronic infection, gut health, and neurological conditions — including complex pediatric cases involving autism spectrum disorder and PANS/PANDAS. He approaches each patient through collaborative decision-making and thorough education, so patients understand not just what they’re doing but why.

Dr. Gill built his practice around the patients who’ve been told there are no answers. He tends to disagree.
