"Dr. Coles has been a blessing to me and my family. I have been his patient for over a decade. He saved me from a bleeding ulcer, found my colon cancer, and has been monitoring all my gastroenterology issues ever since. He is the best doctor in this field and I trust him with my life. You could not find a more competent or compassionate doctor to take care of your internal organs."

"I have been experiencing severe pain in my right upper quadrant since June 2021. I was unable to get a diagnosis through CAT scan, MRI, x-rays from other physicians. Dr. MacCollum had one visit with me, asked many questions, and scheduled me for an endoscopy. Immediately she found a 1 cm ulcer in my stomach and put me on medication to heal it. So within a 2 1/2 week period of time from initial visit to date of endoscopy I was diagnosed. The staff at Arizona Digestive Health were very professional and friendly. The staff at the Arizona endoscopy center, where, Dr. MacCollum performs endoscopy‘s, was the same. I would highly recommend seeing Dr. MacCollum for any gastrointestinal issues you may have!"
