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.

  • “I received exceptional treatment and will highly recommend OSPTA to everyone who needs physical therapy.”

  • “My treatment was very helpful. My overall physical condition improved tremendously. Thanks very much.”

  • “Everyone was so sweet and helped me so much. I hope to never need to come back. But, if I do get injured again, I will definitely be coming back here.”

  • “Great experience – I am pleased with the results and I feel really positive about long-term.”

  • Using a scale of 1-5..”If a choice of #10 were available, I would have used the 10. This is a great place. Thank you all!!!!”

  • “This office was originally recommended to my family by a doctor in Richmond as having a good reputation. We have been very satisfied with treatment. Everyone is very nice and knowledgeable.”
