Dr K. McGrath was wonderful. I have Freedom Blue. I am not switching to a UPMC policy. I hope I will be able to continue to see Dr. McGrath.

Very efficient office. Everyone is very courteous and helpful. In and quickly out. No waiting.

I have found Dr McGrath to run an exceptional practice. The number I call actually is the desk of his nurse practitioner who, in my experiences with the office, has been responsive to my needs. I called on a Monday with a problem and was given an appointment on Friday. In today's medical arena, I find this to be exceptional care.
