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.

He was very personable, friendly, and polite.
Everyone there was friendly and personable. They took care to make sure I was warm and informed. Everything went as smoothly as possible. I drink liquids too late before the colonoscopy, and they were very reassuring that it was all right even though I had to push them back a half an hour.

Dr. Thyssen and his team of professionals were great. I am normally nervous about having procedures such as a colonoscopy done, but they calmed my nerves and we even shared a few laughs. Highly recommend this professional and friendly crew!

Dr. Thyssen
Doctor Thyssen is a wonderful doctor great bedside manor. Getting in to see him is somewhat of a different story. Called for a month after receiving the letter telling me I needed to make an appointment. Left messages, no one ever live, no returned calls. Finally after receiving the second letter telling me I needed call and make an appointment, I went in personally, sat for an hour, just to make the appointment.
