Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Excellent
I hit the age where my Dr wasn’t letting me tell him next year for a colonoscopy. He referred me to Dr Miller. His office has been amazing to deal with in original schedule then rescheduling because I got Covid. I was extremely nervous for the procedure, but Dr Miller and staff at the hospital all made me feel comfortable and took great care of me. From the moment I walked into the hospital, to the front desk clerk, to the nurses, to the techs, specialist, and Dr Miller all treated me perfectly. After I recover Dr Miller came in and we talked about the results, and all was well.

Highest Recommendation- You can trust Dr. Miller
I felt I had the best of care and was treated with kindness and respect from Dr. Miller and his staff. Get your colonoscopy. It was a very easy and pleasant experience. I was made to feel at ease and even had fun with Dr. Miller, the nurses, and the anesthesiologist. Please don’t wait. Get scheduled today if you qualify. It’s simple and Dr. Miller is absolutely excellent at what he does. Plus he’s a super nice guy!

He’s the best
Dr Mark Miller is a very caring gastroenterologist. He understands that these exams are most uncomfortable and provides the best effective care. I have used him for the past 15 years and will continue to do so. I like that he has found alternative medications for the prep and the last one in pills will be my choice from now on.
