"My wife and I both love Dr Singer. He has been around forever which is great because we only see him once in 3 or 5 years. The office is clean, safe, well run, and organized. Scheduling is no problem and thankfully this office is keeping up with technology and the medications. I have recommended Arizona Digestive Health to friends and family and will continue to do so. Why only 4 stars you ask? Good question! After spending all night and morning on the toilet in prep for my procedure, they hung me out to dry in the waiting room for 90 minutes post appointment time. Great waiting bathroom by the way next to the waiting room. I would say I can’t wait for my next experience there, but I can wait."
