Brittany Marks, DPT
Brittany graduated from University of Washington in 2008 with a Bachelors of Science in Biology. She then pursued her goal of becoming a Physical Therapist by attending University of Southern California and graduated in 2012 with her Doctorate of Physical Therapy. After graduating, she ultimately moved to Ellensburg, Washington, for her husband’s career but moved back home to South Whidbey in 2018 when she joined the CPT Team.
Brittany became interested in Physical Therapy after her time working in high school as a student athletic trainer and PT Aide on South Whidbey. Her primary goal is to improve the quality of life for her patients by decreasing pain and restoring function. Outside of the clinic, she enjoys spending time with her friends and family.


Greg Fritz, PT, DPT, RMSK

Greg has over thirty years of experience as a physical therapist and started his career at Island Hospital in 1986. 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. After growing Chehalis Valley Physical Therapy to two clinics, Greg chose to sell the operation to a national rehab company. Longing for the peaceful lifestyle of Fidalgo Island, he returned to Anacortes in 1999 with his wife Janelle and his kids, Laurel and Hans. Greg is known for providing caring, patient-focused treatments with a heart for making friends of his patients. His quality, caring style grew his practice and he selected a like-minded team of clinicians to support this growth. Greg also has busy clinics in Anacortes and Oak Harbor where those communities have learned to expect the same high level of personable, contemporary care.

A student of anatomy and movement science, Greg continues to be fascinated by the human body and his professional interests include musculoskeletal ultrasound imaging in physical therapy, job-site ergonomics, industrial injury prevention, fibromyalgia, TMJ/Jaw pain, balance training and sports/orthopedic rehabilitation. He enjoys flying, art, family, church and laughing. Greg is a real person, with the same real life problems every human body struggles with. As Greg says, “there is no shame projected here. We are in this life together, learning from each other, helping a neighbor to better living.”

Greg was one of three physical therapist recipients in the nation who earned a Pioneer Certificate in Musculoskeletal Ultrasound Imaging (RMSK) in Washington State. This imaging tool is pivotal in the correct management and diagnosis of many orthopedic injuries. Greg regularly lectures at the University of Washington and trains other interested clinicians in the use of musculoskeletal ultrasound (MSKUS) in their practices. He is on the faculty of a distinguished Regenerative Medicine/Orthobiologics innovator (Don Buford, MD).
