"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.

"Very good experience. Great staff; knowledgeable, efficient and pleasant."
"Each time I go in to see Shauna (&/or Dr Walker), they sit, look at me, ask me questions and answer all of mine. I’m as important as my meds and symptoms. I always leave with understanding more, understanding my treatment options as well as changes in my symptoms and how medications work as well as side effects to recognize.
The waiting room and treatment rooms are spacious and comfortable. Wait time is usually less than 15 minutes. My experiences are that all of the staff are friendly, conscientious and compassionate.
I feel fortunate that Arizona Digestive was recommended to me and I feel confident in Shauna’s care."
"2 people did not introduce themselves to me. I asked who they were. The CRNA and Dr. Stein. Didn’t feel very welcoming."

"Excellent care"
"Great Doctors very caring staff"
"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. 👍"
"People are really friendly, and everyone has a smile on their faces..."
"Dr. Vulcano was so nice and took the time to explain everything. When you are scared his kindness really goes a long way. The nursing staff and anesthesiologist were also wonderful and kind on the day of the procedures. His MA was also amazing and made me laugh after the PA scared me out of my mind with a possible dx. That's the negative experience I had. I felt there was no reason to throw out a frightening dx that I hadn't even considered with the statement "do you understand what that means?" which I did. It wasn't that thankfully but the weeks after, while waiting for the testing, were torturous. The rest of the staff from the front desk to the follow up call were fantastic. I will continue to follow up with this office as long as I live in AZ. I can't recommend this place enough. Truly amazing people work here. I'd like to thank them for everything they did to help me through this process."
"Awesome staff and wonderful NP. I would highly recommend Az Digestive Heath East Mesa! I didn’t have to sit and wait forever which is a big plus!!"
"Very caring. Everyone was professional and kind."
"I had an excellent experience with during my recent visit. I love this office, doctor, and NP."
"Very nice job these people really care about the pacence health, and solve the problem."
"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!!!

"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."

I hope Dr. Walker NEVER RETIRES!!!

"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"
"I have the utmost trust in Dr Stein and his partners. The are very kind and professional"
