Very warm and knowledgeable. He stuck multiple needles in my knee. It hurt like hell, but he tried his best not to hurt me. Very lovely doctor & nurse Britney was excellent as well!

He does cortisone shots in the top of my foot and honestly they are done so carefully the pinch is barely noticeable. I'm grateful for these shots as it gives me relief from limping and most pain.

Dr. McMahon took his time with me. I am hopeful that a long present undiagnosed issue will be found and addressed.
