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.

Excelllent doctor, very caring.

Excellence
Dr. O’Hara appears extremely attentive. She is also very thorough. She offers several different options for possible further treatment, from the least evasive to more evasive. I never felt pressured, judged, or undermined.

My ideal primary care doctor
As always, Dr. Ohara was a very attentive listener, making note of my health concerns which she took seriously. Then segued the interaction into a valuable discussion of what plan of action to take that fully considers my personal health goals with her expert medical opinion, which I feel confident about. I could not ask for a better fit for me in a Primary Care Physician.
