I was very impressed by Dr. M. He was very knowledgeable, informational and kind. He sat me down and discussed my x-rays with me and showed me where the fracture was. He gave me clear discharge planning.

I would give Dr. Masem a way higher rating would your scale not top out at "5". He is very personable, provides excellent care, and listens to / answers my questions. I am very grateful for being his patient.
