"I see Dr. Mills for Crohns disease. He is the 8th doctor I've consulted for this condition. Dr. Mills has been the most insightful and the most compassionate physician I've consulted to date. His extensive background treating this condition jumps out from his conversation. He is quick to sort through a number of interrelated digestive system issues and get to a thoughtful conclusion. Most notable to me was that he was focused not only on the treatment but the time it will take to achieve relief - a refreshing change from the norm."

You can actually watch your procedure on screens all above the wall and feel "No Pain". It's an amazing experience to visit Dr Mills & his hospital /facility. All of his staff are as gracious, kind considerate & as he. Dr Mills is an "Expert" on what he has done for my problems. I've been to a few other surgeons that did not handle my situation as well.... I've been going to Dr Mills for over 18 yrs. He has kept me healthy ...Thank you Dr Mills. I'm grateful for you."
