Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

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

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

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

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

Excellent caring doctor. One of the best! He has cared for my elderly mother for several years and has been very caring and attentive. After having her colon ruptured by a previous gastroenterologist, my mom felt confident enough to allow Dr. Karnes to do another colonoscopy. That says a lot because she was not willing to allow anyone to touch her from the traumatic experience she had suffered with the previous gastroenterologist.

Dr. Karnes is everything you could expect from a doctor. Timely, polite, informed, proactive and possessing the empiric abilities of a doctor well beyond his specialty area understanding how it all relates to one another. Having a calm unrushed persona in a world where doctors have to see dozes of patients each day is a feat in itself and makes for a great well-rounded patient experience!
