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.

Genuinely cares
I met with Dr. Haydek before I scheduled a colonoscopy. I discussed my family's Lynch Syndrome history with him and the fact that I have had Colon Cancer twice. Also that all 3 sons have had Colon Cancer.I gained confidence in Dr. Haydek and staff that day, and have yearly colonoscopies and whatever tests he feels necessary to stay ahead of any potential Cancer. Dr. Haydek is very thorough and fully explains the results of his examination.

The epitome of medical professionalism
I have had many medical specialists in my life, and while most were very good, none approached the level of professionalism displayed by Dr. Haydek. I first met him when we moved to this area and I needed a doctor to monitor my Barrett's Esophagus. At that time, I'd lived with this condition for 10 years and was under the impression that if it ever changed to esophageal cancer, that was the end of the road. Dr. Haydek explained to me that with the type of Barrett's I had, this was far from true and explained the available procedures should this occur. He lifted a huge weight off my mind with this and I'll be eternally grateful. He has performed several endoscopies and colonoscopies on me, and each experience has been as pleasant as possible. I highly recommend Dr. Haydek and GI Associates.
