Dr. Schwartz is very knowledgeable about my condition and makes sure all my and my wife's questions are answered before we leave.

Dr Schwartz is a great dr very knowledgeable, helpful. Just need to be quicker when getting paperwork filled out and back to patient. I think Dr Schwartz is so busy between hospitals he needs more help so he can provide more time with his patients. Upmc expects appts to be only 15 minutes long per person that is not possible to give good care to us patients in that minimal time. I'm very thankful to have him as my dr.

I called and left two messages with no return call. I emailed via my upmc and got a return message within hours. this is not a reflection on dr. swchartz, he is wonderful and would recondend him. also the female fellow was awesome! (sorry, can't remember her name).

I've been coming to this particular office for many years and everyone there is always professional, nice, and helpful.

June 08, 2017

the wait to see the provider was 2 hours that is unacceptable and the office should call and inform you of the delay so you can arrive later

The medical staff and doctors are top notch and have been the main reason my chronic condition has been so well controlled for the past several years.

I can't say enough good for Marc and his staff. He really took the time to listen to me and help figure out my health issue.

The visit was great, staff and doctor were attentive to my questions. I was disappointed in the tardiness of the doctor, as my 8:30 appointment started at 9, when no one else was in the waiting room and I was likely the first or second appointment of the day. The nurse got my vitals by 8:27, but the doctor did not arrive until 9 to see me.
