Professional and caring

March 10, 2017

Dr. McGrath has always been professional, attentive, compassionate and most notably extremely knowledgeable about the condition for which I sought his opinion.

March 10, 2017

I have had nothing but very favorable interactions with Dr. McGrath. He is a sensitive and patient care provider.

February 24, 2017

Dr. McGrath was very nice and definitely showed an interest in explaining my problem and how to deal with it in a way I could easily understand. I just wish all doctors could be more like him.

February 17, 2017

I was highly impressed with the Digestive Disorders Clinic. Dr. Mcgrath was extremely professional. I appreciated his attention to detail and willingness to listen to my full history, including his very practical plan.

Very professional and informative

February 03, 2017

Dr. McGrath is EXCELLENT.

February 03, 2017

Dr. McGrath is the exception rather than the rule as far as physicians are concerned. He consistently spends time with me, sits down, listens, and is genuinely concerned. He never buries his head in the computer while I am talking. He never rushes me and always involves me in the plan of care. UPMC should consider itself lucky to have a physician like Dr. McGrath.
