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'll be 50 this month so my primary referred me to Dr. Zerega for a colonoscopy. I was a bit nervous going in as I've made it this far and have never had a single surgery or procedure. He was very personable and put my mind at ease. In fact, the entire staff was great. I was in and out in less than 2 1/2 hours and the procedure itself was less than 30min. No pain, discomfort or downtime and the end result and pictures were great. I would definitely recommend Dr. Zerega!

My wife, 82 years old, has many health problems and needs to visit various doctors. I am very impressed with the high professionalism of Dr. Zerega, combined with exceptional friendliness and detailed examination of her illnesses. He spent more than one hour with her, together with his nurse made the necessary tests and found out the reasons of her poor conditions. As a result of following the recommendations of Dr. Zerega, my wife’s conditions significantly improved.
