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.

We LOVE Dr. Dimas!!!
Dr. Dimas is THE BEST OF THE BEST!! She replaced our daughter's pulmonary valve in May of 2021 and what an improvement we have seen in her overall health and well-being. Not only is she one of the most talented and smart heart surgeons we have ever dealt with, she is as nice and personable as the come. We LOVE Dr. Dimas and highly recommend her to anyone that is facing a heart issue that requires surgical intervention.
