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.

I don't have enough nice words to say ab ut Dr. Cassimatis and the staff at this facility. Friendly, professional, accommodating - I just always have a great appointment and don't even get me started on Dr. C. and the ease of having the dreaded colonoscopy. He is so caring -just the absolute best!

Dr. Cassimatis is a great doctor. I have had GI issues for years and prior to my recommendation to see Dr. Cassimatis, was being treated by a CRHC doctor for many years with minimal and sporadic improvement of symptoms. Dr. Cassimatis changed this! He accurately diagnosed my conditions and prescribed treatments that have helped to alleviate my symptoms and ease my discomfort. My stomach feels better than it has in years. He listens, he cares and knows what he is doing!
