Michael Harris

Michael Harris,
Owner/Physical Therapist
PT, DPT

Michael grew up all around the country as a military child until his family settled in coastal Virginia. Michael graduated with a B.S. in Exercise Science from Old Dominion University. Following his undergraduate studies, Michael earned his Doctorate of Physical Therapy from Radford University in Roanoke, Virginia. It was here that he developed an affinity for the Appalachian region with its good people and wholesome communities. Michael is now a proud resident of Cumberland Gap, Tennessee.

His career as a physical therapist spans the rehabilitation continuum from skilled nursing care to outpatient orthopedics. His clinical background has given him the ability to treat patients of all ages and fitness levels with both non-operative and post-operative pathology. He is driven professionally by encouraging the pursuit of well-being. Michael is most fulfilled by equipping patients with the knowledge to make meaningful and lasting improvements to their quality of life. He believes these improvements come through empowering patients with positive habits, rather than encouraging dependence on unnecessary pharmaceuticals and injections.

Michael enjoys spending his time with loved ones, with nature, and listening to some beautiful string music.
