"Dr. David eased my fears of having a colonoscopy. He was very understanding and patient with me. I went to him two other times and always had a positive experience with the procedure but it’s been eight years and I was nervous to be put to sleep. He worked with me and eased my fears. I am not dreading the colonoscopy anymore. I highly recommended Dr. David."

"I recently had a visit with Dr. David concerning a medical issue I was having, he scheduled a test and discovered an infection that I have had a long time, long before I moved to Arizona 3 years ago.He treated it with antibiotics and now I’m not only feel a lot better but I was able to discontinue medicine that was prescribed to me 10 years ago when I lived Detroit. He and his staff have been very good with follow up calls also. Thanks Dr. David."

"Dr David initially questioned why I was seeing a second GI in two years; this is understandable. However, after reviewing various prior GI studies he recognized the need for a more thorough examination given my existing symptoms. He was straightforward and communicated clearly the initial imaging required, a treatment plan for some immediate relief and a follow up appointment plan. I have a follow up with his NP/Nutritionist for imaging results and a further treatment plan. I find his approach to be honest, efficient, and professional."
