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.

Dr. Wiener is very experienced.
He was able to quickly and thoroughly review the multitude of my previous tests and ablation procedure, and gave me all the information I need to make decisions about my care. He asked if I had any questions and genuinely cared. I feel that this is an electrophysiologist cardiologist that I can completely trust. I greatly appreciate that I was able to have the opportunity to meet with him.
