Dr. Marshall Rennie has been a practicing physical therapist since 1996 and has devoted his entire career to OSPTA, where he is Vice-President. Although specialized within his practice, Dr. Rennie stays current with research on all areas of orthopedics. He is active with clinical education of students; with doctorate level physical therapy students and physical therapist assistant students. Dr. Rennie was a contributing author to the text, “The Low Back Pain Handbook” (1999).


When not at work, Dr. Rennie enjoys a busy life with his wife and young children; helping him appreciate the demands (and joys) his patients have in this aspect of their life as well.

I know patients need to restore functions so they can return to the activities they enjoy and need to do. I strive to provide friendly and compassionate care as I work with patients.

My goal is to make the best choices when implementing therapeutic interventions for each patient based on their impairments.
