This was my first time going to UPMC and seeing this doctor. Everyone was so friendly and welcomed me. I have never felt so welcomed from any place like I did with this office. I would definitely recommend anyone here.

I have had other family physicians and Dr. Mercado is by far the best. He is very attentive and sensitive to my meds and if there's a specialized problem, he makes sure you get to the Dr. That can best help you. I would refer anyone to him!
