"Appointment went well with a short wait time. The PA was kind and caring. It was a short visit but good."
"Staff was wonderful. Great experience overall"
"Clean office. Front desk staff very nice and helped with co-pay explanations. Morgan Binder was very nice and patient to listen to my concerns and answer my questions. I did not feel rushed and in no way felt like I was just another number to collect money from. Highly recommend this office."

"Dr David is the best in the Valley. He cares for his patients and invites questions."
"You wouldn't think this would be a pleasant experience, however, everything about facility was perfect. The check in process was quick, and maybe a 5 minute wait time at best. First thing I was offered was a warm blanket with a smile. The nurses were so friendly, caring and genuinely caring. Both anesthesiologist checked in and thoroughly explained their part in procedure, followed by the physicians. Recovery was quick and I was sent home. Quick, easy, no pain……. Do not put off routine colonoscopy and endoscopy exams. It can save your life! If you need a gastrointestinal doctor, go to Arizona Digestive Health. All doctors are great, and if you are scheduled for a procedure at Arizona Endoscopy Center, know you will be in good hands. Helen Brejtfus"
"Doc was great. Procedure and processing was smooth. Staff was very caring."
"I initially went to American Digestive Health about 5 years ago in 2018. I must say that my visit with Dr. David was was very positive. He has a great bedside manner and he was and still is very thorough while explaining everything. I felt very comfortable with being under his care. He visited me both before and after my procedure. All went very well. Moving forward to around Oct 2023 I received my first reminder that it was time to come in again. I immediately began calling the office to try to schedule an appt. Here is when the nightmare began. I was on hold for very very long periods of time, sometimes strangely the line would disconnect. I would try to call again and would go through the same problem. I mentioned this issue to my PCP who had originally referred me to Dr David. He was not sure of why this had been happening but really wanted me to try to stay with Dr David because at this point I was frustrated and ready to look elsewhere. However I like Dr David very much as well, so I decided to stay and keep trying. Eventually after several calls I was able to leave a message and at some point in late November I finally received a call only to be told after answering too many health questions that no appointments were available until 2024 and the schedule was not even open yet. This, to me was crazy!! So I was left to hope that someone would call me back in January. After finally getting scheduled. All was good. However, several days before my appt I received a text asking me to confirm my appt. I immediately responded to confirm. Then two to three days later I receive a second letter (Final Notice) asking me to schedule my appt. Imagine my confusion after my experience so far. I was very frustrated but immediately called the office and left a message for someone to call me so that I could be sure all was set even though my procedure was already scheduled. Of course no one called. I went to my scheduled appt and while sitting in the waiting room, lo and behold 3 minutes before they called me back for my procedure, I get a call from the office finally returning my call. Minutes before I would soon be under anesthesia. I only had time to tell this person that I was already at my appt and hung up. To be very clear, I have absolutely no complaints about Dr David. He is great! Thanks to him and the lovely nurses at Az Endoscopy for taking great care of me!! My complaint is the schedulers and the process of getting scheduled via ADH. It should not have been that difficult. There seems to be a disconnect somewhere in the entire scheduling process. Please fix that issue!"

"Very professional"
"The only area for improvement would be for the person or persons in charge of checking your insurance do a better job. My insurance representative, was kind enough to call and give them a IC number verifying my coverage so there would be no upfront cost to me. This scenario has happened the last five times, and I never paid upfront. It’s very frustrating."
"Quick and easy process. Staff professional and friendly. See you in another 5 years."
"Dr McCollum is a lovely lady. Spent time with me and listened to everything I had to say. She has great answers and great treatment plans also. She gave me a colonoscopy and endoscopy at the same time to avoid having me go through anesthesia and discomfort twice, even though a doctor gets paid more for doing them separately. She's great! Dr McCollum is a phenomenal and highly knowledgeable doctor as well. I highly recommend her! She has a lovely smile too."

"Dr Schwartz is terrific. He listens attentively which is refreshing these days. He addressed all concerns. And he is kind. I felt so at ease and comfortable. His front office is equally professional and friendly. So that is a home run. So glad I found this practice."
"Dr. Schwartz and his staff were all professional and knowledgeable. His bedside manner was old school. He paid close attention to my needs and took ample time with me all 3 visits. He made me feel like I was in good hands despite me being late my first visit because I’m new to the area and went to the old office. Even my first appointment he took his time with me. Maybe I’m just jaded from the cattle call approach from doctors in California but so far every doctor I’ve seen in Arizona have all had this old fashioned bedside manner. Thank you Dr. Schwartz for your services and your friendly staff."

"I am so glad i got a referral for Dr Schwartz. He explained to me what potentially happened to me. He spent lot of time explaining me things and making sure i understand everything going in my body. I am taking a lot of positivity out of my appointment. My hope and confidence to stay healthier has increased a whole lot. And even if something happens to me again, I know Dr Schwartz will make it right. Thank you very much Dr. Schwartz."

"Dr Barbara Macculloc was very helpful and I would recommend her to anyone needing a gastrointestinal doctor."
"Dr Schwartz is a great gastrointestinal doctor. He explains everything that you're going to go through in great detail and it makes you feel completely at ease.

She made time in her busy schedule to see my husband when one of his tests came back questionable. She was patient, informative and kind, made us feel completely at ease. As a last thought, we are grateful for Dr’s like her who are compassionate and caring. John and Tena Roberge"
