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.

Just what I needed
Great communication and meeting of the minds with Dr. Dennert on my healthcare approach and future care. She is a joy to work with.

Dr. Dennert and the office staff are amazing!
I have been seeing Dr Dennert for many years and am so glad that I'm able to be a patient here. Not only is she caring and considerate but she is professional as well. I'm going through a difficult time in my life and we not only talk about my condition but she is also concerned about my family. I feel blessed to have her as my GI.

Amazing experience
Dr. Dennart was very thorough and made sure that all my questions were answered. She even took time to dig a little deeper into things that I would not have thought mattered in my treatment, but as we discussed them, I realized it did if she had asked me those questions I would’ve never been able to get the proper treatment that I needed highly recommend, her to anyone seeking Gastro help .

Dr. Dennert is simply magnificent.
Doctor Dennert has performed 2 major procedures on me personally. She has an extremely warm and calming bedside manner and her professionalism is obvious to her patients and any staff around her. It is genuinely difficult to find the words adequately express my respect for her. Dr. Dennert comes with the highest recommendation I can give. Trent Franks
