Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

I knew Dr. Mezei from working at St. John’s Mercy back in the 1990’s. Dr. Mezei later moved his practice to St. Luke’s. I needed a cardiologist in 2012 and chose Dr. Mezei. He closed his practice this year and will be sorely missed. He was everything you hoped and needed in a physician. He was smart, articulate, instructive, supportive, caring, protective. Prefect. Thank you Dr. Mezei for the wonderful care you gave me and others. You will be missed.

I would recommend Dr. Mezei without any reservations. He is courteous, but he is thorough in his discussion of his course of treatment. I fully believe that through Dr. Mezei's competent and insightful knowledge, he diagnosed my medical condition and through his course of treatment, I avoided further serious medical issues.
