Who We Are

Greg Fritz, PT

Greg has over 24 years of experience as a physical therapist and started his career at Island Hospital in 1986, after receiving a degree in physical therapy from Loma Linda University, in Loma Linda, CA. He ultimately desired the freedom and challenge of private practice so he moved to Chehalis, WA to develop an industrial rehab center and a clinic focusing on sports and orthopedic injuries. Longing for the peaceful lifestyle of Fidalgo Island, he returned to Anacortes in 1999 with his wife and two children.

Greg has opened, owned and operated several PT clinics, currently focusing his efforts on Anacortes Physical Therapy and Coupeville Physical Therapy. He is co-founder and chief executive of Skagit Island Rehab Group.
