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.

Lied to get me to come to Cleveland clinic with other specialists! Said all the testing would be done there or ordered here at home! Don't believe a word he says! The specialists don't even know why you're coming!

×Post a ResponseAre you Dr. Sullivan?
I saw Dr. Sullivan at Cleveland Clinic as a part of the National Consult Program (NCP). The NCP promised me that Dr. Sullivan would help me understand my issue and work with me to find help with it. I flew to CC for this help, and Dr. Sullivan showed zero interest to help me. He fobbed me off to other doctors instead, both of which were perplexed as they couldn't help me and were up front about it. One even cancelled the appointment immediately and said I was in the wrong area. I tried to tell that to Dr. Sullivan, but he didn't care in the slightest. He flat wasted my time. I highly recommend going to Mayo instead if you need care.
