SHC Patient, Jun 2014

I was not happy with his answers but he was right. I would liked to have my requested testing done but he was not did not feel needed at this point.

SHC Patient, Apr 2014

Doctor had little respect for my symptoms/concerns & little knowledge about Celiac in real world scenarios.

SHC Patient, Mar 2014

Dr. Gray is the best ever! No gastro. has ever treated me with such care & as a person first.

SHC Patient, Jan 2014

I had a very good experience with Dr. Gray. Normally, I don't fill out surveys; however, he was exceptional. That's why I'm taking time to fill out form.

SHC Patient, Dec 2013

Dr. Gray assumed I was competent and intelligent, spoke with me NOT at me and asked multiple open ended questions. My wife, an RN was with me and she was treated a peer professional - Thank you!
