Gary's the best very knowledgeable about me

I have always had good experiences with Dr Gruen . He is an excellent doctor and person. It is because of him that I am able to walk.

June 20, 2019

couldn't make appointment for next year but have in past. X-ray report was different than what doctor and assistant explained to me. Dr Gruen is a marvelous MD and my husband I are truly grateful for his remarkable care and unrivaled skill.

June 20, 2019

I was referred to Dr. Gruen, and he did not disappoint. I didn't have to wait long to see him at all. In fact, I was in and out by the time I'd still be waiting to see the doctor I saw previously, and he was still thorough, kind, and seemed well-educated. Dr. Gruen reviewed my medical records prior to meeting with me, making him familiar with me. I will definitely recommend him.

Dr Gruen is an outstanding physician. upmc is lucky to have him.

April 25, 2019

Dr Gruen is by far the most personable, respectful, knowlegable and caring provider I could ever imagine being taken care of. He is thorough with his explanaitions of my medical needs and speaks with a calmness about serious surgeries that helps me feel at ease with the procedures. I feel like Dr. Gruen should be the highest paid provider in the upmc employment database..He is a shining example of the highest quality care available through UPMC.
