Patient Comments (2)
in Flagstaff, AZ |
Can't say anything about Doctor because I never got the chance to see Dr Overhiser because the person who answers the phone told me that my Medicare would not pay for Dr services because I saw another Gastorenterologist one time which I didn't care for. The person answering phone at Northern AZ Gastroenterology was very rude, and after I talked to Medicare and knew that rude girl was wrong on turning me down from seeing the Doctor I called back twice and she puts me on hold forever. Bad attitud
He has been extremely open and honest about my health and my treatment options while also respectful of my emotions as we work through my illness. He explains options thoroughly and in a way I can comprehend. I trust him completely. He and his assistant are always available to talk to in a timely manner. He is a pleasure to work with and I could not ask for a better doctor.
