I am beyond happy with Dr. Mammen it has watched me closely, and feels it is important to go to the next step. Doing a biopsy. I am so blessed to have been put into his hands I would highly recommend him to any of my family or friends. I have received the upmost care and respect from Dr. Mammen and his team.

He is a very knowledgeable and caring doctor. He is always ammenable to questions. He has brought me from almost losing my vision in one eye to a a near perfect vision because of his knowledge and because he care. I have never felt rushed during my visits.

so happy that I could get help for my eye problem in the E.D. at UPMC Presbyterian hospital. The resident was wonderful in the E.D. And got me to the right doctor. They were both the Best of the Best!! Thank You!!!

Office staff and Dr. Mammen were all courteous and professional. The problem I have with seeing this doctor, is the wait time. I waited over an hour, in the waiting room before I was seen. At another visit, I waited over 2 hours, then had to leave without seeing the doctor, because I had to go to work. I also work in healthcare and would never think of having my patients wait that long to see me. Why the inefficiency? It feels disrespectful of my time.
