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. Onanyan is a kind and knowledgeable physician. I am grateful for MDs who are keeping me alive!

Dr. Onanyan is the best speciality provider I've seen in some time. He is the ONLY provider I've spoken to that did chart prep, and was knowledgeable of ALL of my medication conditions. He was extremely kind, and had the best beside manner. I felt very supported after our visit and wish he treated other conditions. He is truly an example of what a provider should be.
