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.

Lost 2 teeth
Kept going back multiple times over months complaining about discomfort and food collecting under a tooth with a crown and bridge. At one visit he filled the tooth. Food collecting and discomfort continued and got worse. He referred me to a periodontist who told me that the tooth was overtly decayed and questioned why O’Brien even sent me to him. He said that the filling was applied over decay. The tooth disintegrated and the root had to be extracted surgically. On another tooth, O’Brien performed a root canal and a crown. After couple years food started to accumulate under the tooth. He sent me again to the periodontist who told me that the root was cracked as a result of the root canal and that the tooth was dead and had to be extracted. He questioned why O’Brien sent me to him. Daniel O’Brien is not an endodontist and is not qualified to be performing root canals. I moved to another Dentist who found other issues with crowns that O’Brien installed...

This is such a great place. The staff very nice, place is immaculate for cleanliness and Dr. O’Brien is a much like an artist, when it comes to his work. Just moved into the area tried other places before I found Dr. O’Brien. Took awhile and I couldn't be happier.
