"I saw Shauna as Dr. Vulcano was not available. She is amazing. She explained everything to me and spent time telling me about any test that I might need. I would definitely see her again if needed."
"Dr walker is very caring and compassionate. Recently had a procedure done and everyone was so nice and comforting. Finally found a great place to get digestive issues resolved. Thank you to everyone who assisted in my care."
"Fantastic Doctors and staff! They go that extra step in dealing with your care! Thanks to that, I was in for my 1st office visit 8 years ago, and instead of going forward with a colonoscopy, Shauna admitted me to Banner with Stage IV ovarian cancer! Yes, I did get my colonoscopy, eventually. An easy process!"
"I have had succesful visits with two separate doctors and felt good about them. I especially like that a paper is given me of the things we spoke about that is a good reminder to me."
"Probably the VERY BEST Dr. Visit that I've had in my 56 years. Lindsey has been AMAZING. Listens, cares, explains and then helps! I would 100% recommend them for any digestive issues! I feel so lucky to have her as a provider!!!"
"My first appointment so I do not know much about how they will continue. I saw a NP, not a MD. She went over my problems with me, made a couple suggestions and ordered imaging. I thought she was very thorough. Hopefully this kind of caring treatment will continue."
"I have been a patient for over 8 years. Very professional and personal focused services. Ms. VanDam has provided very thorough explanations relating to my issues and also explains the results and options in detail. Highly recommended."
"I had gone to see Dr. Stein in 2013. While I didn't see him on my last visit, the gentleman who got all my information and the woman, who scheduled me for my January 2023 appointment were both wonderfully professional. They answered all my questions in a simple and easy-to-understand explanation. I'm definitely looking forward to seeing Dr. Stein in a week!"
"When in for an endoscopy. Maria my pre-proceedure nurse was absolutely fantastic(didnt even know/feel she started the IV). Brian( anesthetist) was very kind. Dr. Walker was outstanding, through and explained everything. Samantha (post-proceedure nurse) provided excellent care with outstanding professionalism. This team knows their stuff."
"I had an appointment with Shauna who was very professional and pleasant. She took her time with me making sure all my questions were answered thoroughly."
"Dr. George Walker is THE BEST! So IS Lindsay, his NP. Thorough, professional, kind and great listeners. Totally satisfied with this Group. Grateful!!!"
"Had a procedure done recently with Dr. Umar and "the staff"... I could'nt express how professionally everyone was and made me feel so comfortable during the whole process.. That facility is AWESOME!! I appreciate you all...."
"I think the staff and nurses are very friendly. I love Dr. Stein and his N. P. Shuana. They make me feel very special and concern about my needs and what issues I'm having with my health."
"I had digestive problems for 2 weeks with severe gas and pain from food poison. Met with Lindsay and she gave me famotisine after 4 days I got some relief."
"Lindsay Van Dam was amazing she took the time to review everything and explain the next steps that needed to take place in detail. I would definitely refer anyone to her."
"AZ Digestive is wonderful with caring staff. Lindsay especially took the time to listen to my concerns and set up the appropriate appointments. Very pleased with the care I have received thus far."
"I have always had great experiences at Arizona Digestive Health, the staff is nice and helpful. I had an appointment with Nancy, Dr. Zierer’s associate she handled my concerns and took the time to listen to what I had to say."
"Dr. Stein is a professional who listens/advocates for his patients. I decided to schedule a visit with him after reading the positive reviews and I was not disappointed. On the day of my appointment, the receptionist was friendly and check in was simple. Maria, the medical assistant who brought me back to the exam room, was friendly, attentive, and professional. Dr. Stein walked into the exam room accompanied by an assistant who takes notes throughout the visit. This was great as it allowed Dr Stein to have a natural flow of conversation instead of having to continuously stop to take notes. I mentioned to Dr Stein some testing I had done and he was able to locate the results and share them with me during the visit. I left the visit with a plan in place and with the feeling that I was in competent hands."
"Everyone at the office was terrific. The girl at the desk was friendly and helpful. Troy was a pleasure and very much able to put me at ease. Shauna was great as always. She seemed to ask all the right questions and had answers for my questions. All in all, it was a great experience. 👍"
"The team is absolutely amazing. I have serious anxiety when it comes to doctor visits, so much that I have not seen a doctor in over 10 years. However, Dr Stein and his team made me feel completely comfortable. I would definitely recommend to family and friends. :) To Dr. Stein and his team, thank you so much!"
"I can't say anything negative. From calling and scheduling my appointment, checking in for appointment, meeting with Dr. Walkers assistant and Dr Walker himself. It was a very pleasant experience. Highly recommend!"
"We were treated with respect and professionalism. I'm so glad we went to ADH: East Valley we got answers and did not feel like we were just throwing one antibiotic after another."
"I am having swallowing plus lower stomach issues. These problems were addressed by the medical staff at AZ Digestive Health. I left there feeling much better going forward. I would highly recommend these people to anyone having Digestive Health problems."
"What a professional office from beginning to end. I was taken in a little early for my appointment. Was seen right away by both the MA and the provider. Received a phone call from the office within a day to set up my procedure and received all the prep information right away. This is my second visit with this office and couldn't be more pleased."
"I have gone to this office for a little over a year. Dr Stein is wonderful and has an excellent way with patients. The staff for procedures are all top notch making sure you're taken care of well. I also saw the physician assistant Shauna Binette. She took great care of me and addressed all my concerns and helped me when I wasn't feeling well. Definitely recommend this office... Use the portal to communicate. It makes things go much smoother."
"I was really pleased at how everything turned out. The IV is my biggest fear, but my nurse was incredibly gentle and was able to get it in the first time! Only the tiniest bruise! The doctor and crew were funny and easy going. Everyone was wonderful!"
"Excellent care by Dr Collins during a critical GI bleed. His professional timely attention and follow-up with explanations in lay terms gave us encouragement & confidence that we were in good hands. Following appointment with his staff, especially Shauna, nurse practitioner, showed care above and beyond ordinary. She took a personal empathic interest, even to the point of arranging a change of appointment with another specialist, so we did not need to handle that. Wonderful caring competent team; we feel fortunate."
"Love Dr Stien and Staff!!! Been going there for 10+ years now. My boyfriend liked him so much that he started going there too!!! Dr Stien listens to you and is very thorough. I would highly recommend him for anyone looking for a GI doctor."
"They are the best ! Dr. Walker and Dr. Collins have provide the very best care. I highly recommend them. I have recommended them to my family members. That says it all."
"Arizona Digestive Health East Valley has friendly and professional staff and doctors. I’ve been going there for a while and I’m grateful to find a good place that cares about my health."

"Arizona Digestive Health is an outstanding health provider from Dr Ziere to his PA Shauna Binette. Front office staff So friendly and helpful! I was greatly impressed. Thank you Arizona Digestive Health for your excellent care!"
"I have recomended Dr Stein and his NP. Both are awesome. They take their time and answer all of your questions. I do have to say though that the front office needs to learn how to be more courteous with patients."
"The visit to Dr Vulcano's office, Digestive Disease Consultants, was a very good experience. He was pretty much on time and very professional. He performed an endoscopy at this office and it was quick and painless. I would recommend Dr Vulcano in a heartbeat!"
"The facility is a little small especially when it comes to clients that require assisting disability equipment ie:wheelchairs * (especially), walkers, electric wheelchairs/scooters.. The waiting area is way to small especially if you need to bring someone with to assist The staff are wonderful!!! however I experienced some problems receiving "timely" information/forms that needed to be filled out prior to procedures/appointments and there seemed to be some communication difficulties between providers, the facility is way to small for the volume of procedures being done!!! Other than that above mentioned it is a great crew to work with. Thank you for everything!!! Jennifer Klick"
"I just want to thank EVERYONE, from my appointment to my procedure. Everyone there has been beyond amazing. As for my procedure, I was nervous. Everyone there was so nice and accommodating. I felt very comfortable and well taken care of. I was only sad to leave, lol... I wanted to sleep longer jk. I was glad to go home and that it wasn't as uncomfortable as I thought it would be due to the care that I had. THANK YOU TO EVERYONE! FROM THE BEGINNING TO WHEN I WENT HOME. Thank you Dr. Zierer"
"I have very complicated GI issues. In the hospital years ago, this nice Dr came in to check me.....that was it....I asked what group he was with and if they are accepting new patients. That was over 13 yrs.ago. Dr. George Walker is amazing, intelligent and sensitive while being professional. Great office staff on top of it!! I hope Dr. Walker NEVER RETIRES!!! Susie"
"Dr. Ramsey Umar and his team are awesome! From checking in to his office for my appointment to checking into the surgical center for my procedure and discharge, everyone was polite and caring, thank you all. And Dr. Umar, patient, kind, responsive and competent! Yes, I am happy ❤️ Thank you all .... Bob G"
"Best experience in a digestive specialist’s office I’ve ever had. I was referred to Dr. Walker. He was very helpful. He listened and explained things very well. We had a lengthy exchange of info, just like an investigator would, in an effort to get to the bottom of my medical issues. Very well-spoken, dow to earth, knowledgeable and informative doctor. The front office staff were friendly and welcoming and most of the back office staff were just as lively. Not one person was short with me, impatient or dismissive of me. I’m grateful my primary doctor sent me here."
"My experience at East Valley Endoscopy was actually a fun and relaxing procedure. Thanks to all of the staff, Dr Zierer was so friendly, understanding and patient.They all took the time to explain everything about the procedure, even though I was nervous. I felt comfortable going in for the procedure and had no worries that I was well taken care of. Thank you to the whole staff for making my procedure fun, relaxing and worry-free. I will highly recommend you to my family and friends. See you in 10 years. Sincerely, Sonja Smith"
