I felt like I was heard. This problem has been going on since April 2024, when my husband brought me to the emergency room. Dr. Parsons was excellent in asking what brought me to this point, how I got to this point, what other doctors had said, other treatments I had tried, etc..

I have always had good experiences at the clinic, but this was one of the best. Pay William P arsons whatever it takes. You are lucky to have him on your staff. Same goes for all of the Ortho people I had contact with that day.
