"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."

"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"

"Alay treated me right. Answered my questions and how I wad being treated."
"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"
