"I have been a paitent of Dr. Wells since the early 90's. Recently I had an issue come up and called the office. Turns out it was not as severe as I thought. Dr. Wells put me on a prescription after speaking with me in detail on the phone. The issue was resolved quickly. So what's the big deal? He called not once , but two times and left messages for me wanting to know how things were going and if I had any questions. When was the last time a specialist took the time to call personally to see how you were doing under his/her care? I can't remember EVER having that experience. Every 5 years I'm in the center for a test and the staff could not be more professional or attentive. I recommend Dr. Wells and Arizona Digestive Health strongly."
