He is by the far the most thorough and attentive doctor I have ever seen. I was impressed with his empathy and bedside manner.

Dr. Merrill and staff were very professional, friendly and made me feel very comfortable in the office and during my outpatient procedure. They also made my husband feel like he was a part of the process. I really appreciated that!

I met this Dr. while treating my wife in arrowhead hospital. This doctor and his office likes to refer running a business instead of treating people. And that is exactly words out of his office manager's mouth. So when it comes to personal care and treatment I would look elsewhere!

Dr. Merrill is very knowledgeable when it comes to GI issues. I saw him for the first time in May 2016. After a very short wait in the lobby, I was ushered into the exam room by a wonderful and very professional nurse/PA. She took my vitals and necessary information and in short order Dr. Merrill was in the room. He explained in great detail (with exquisite bedside manor) what I needed to do to get my issue corrected. He is an extremely personable physician. I would recommend him to anyone.

Dr. Merrill was great from the first consult through the actual Colonoscopy. He definitely made me feel much less stressed and more comfortable with the procedure and the process leading up to it. Absolutely no issues and no pain or discomfort at all!!!
