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. O'Reardon is the ONLY doctor who stuck with it and me to get my hypertension under control. He is very accessible and caring.

Laughed out loud at me and my condition ( obesity) in front of three interns that were shadowing him. Walked out of the office with my client, who was there for a check up in complete disbelief how I was treated. I felt ashamed and mortified. Never again will I set foot it that office.
