“As a physical therapist, I am a teacher and a coach. I do not see my job as making someone better but educating and equipping them to reach their full potential.”

Ray is a graduate of Ohio University's Doctor of Physical Therapy 2011 class. Since then, he has been on a continuous journey to deepen his knowledge of the human body and impairments that come with it. He became an orthopedic specialist in 2014 and completed his fellowship training in orthopedic manual therapy in 2019 through the North American Institute of Orthopedic Manual Therapy. It was during his fellowship training that he was introduced to breath work and the powerful and beneficial effects it has. He completed the Breathe Your Truth coach certification program in 2021. He currently sees both orthopedic and breath-related patients at Wildwood Physical Therapy in Portland, OR. Outside of work, you can find him on his bike, mastering his own breathing practices.

My exploration of a breath work program with Breathe Your Truth grew from my passion of being a yoga instructor and a long career as a physical therapist. Too often, we see patients struggling with stress, frustration, and anxiety which gets in the way of their rehabilitation and returning to what is important in their life. Managing your breath can be a simple, accessible way of naturally addressing these challenges with the help of a coach and guide working alongside of you.
