Dr.Amed is very personable. My visit was a very pleasant experience. The procedure went very smoothly and comfortably.
The office was very friendly and helpful and enjoyed talking to them . When Dr Singh came into the exam room ( on time ) he listened intently and put me at ease with his initial diagnosis( not cancer ) and told me the tests that I needed done . It was a good experience.
I have been seeing Dr. Tharalson for almost 25 years. In my humble opinion, Dr. Tharalson is one of the best gastroenterologists in the Phoenix area.
Dr. Collins is a wonderful doctor! He is very friendly and i really like and appreciate how he takes the time to fully explain things to me!
Very friendly staff, it was a pleasure to meet Dr. Mahajani. I feel confident that I will be in good hands. Thank you
My endoscope went well. Came in to let know what was found & I shouldn't have the problems I've been having. Very nice demeanor & honest. I'm supposed to have another procedure maybe in the fall & would most certainly have him do it. If you're recommend to have this done by them, go & get it done. You won't tegret it.
Recently, my doctor, Dr Sawyer, Retired and Dr. Grade took over my care. I found him to be polite, informative as well as really warm. I made a great choice.

I have gone to Dr. Grade for years and honestly would not want to go to anyone else. He's kind, professional, thorough and anything else you want your gastroenterologist to be. I just had my most recent colonoscopy and the nurses and anesthesiologist were fantastic as well. If you're looking for a gastro Dr., I highly recommend him.
Dr. Drewitz and the staff at Phoenix Endoscopy are phenomenal. I had a great experience. They are very friendly, professional and efficient. I wish I could give a rating higher than 5 stars, they deserve it.
The Dr and staff were very courteous and professional they made me feel very comfortable pre and post Colonoscopy procedure.
Dr. Foley is the nicest and most informative doctor I have ever been to
I wish him the best success in his medical career
