Justin Peterson

My name is Justin Peterson and I’ve lived in Washington state my whole life. I grew up very active in sports playing football and track and field through college. Through sport injuries is how I got involved with MAT
being treated for the first time when I was 16. I’ve finished the specialist program and am half way through the mastery program. MAT has been my biggest tool as a physical therapist to helping improve my patient’s strength, stability, and mobility and help in reducing pain.
