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.

A Fantastic Internist.
Dr, Dibenedetto has taken very good care of my parents for the past 30 years. He is professional, very knowledgeable and thorough. I had also seen him myself many years ago when I lived in the area and was also treated extremely well. A fantastic doctor.

Great Doctor & Staff
Went to Dr. Dibenedetto last year for two crowns and back again for a tooth that needs root canal. I am very happy with him and the staff. They make you feel comfortable & your well taken care of. Dr. Dibenedetto seems really knowledgeable and has done great work on my teeth. This last tooth I didn't make easy for him to figure out which tooth and the issue, but he did figure it out.

We are very fortunate to have Dr. DiBenedetto for our Internist! He is always there for us and cares. Over the years whenever we call to make an appointment for any health issure we were concerned about we always got an appointment to see him on that day. Whenever we have lab tests done he calls if any of the results are out of range. If all are within normal range his secretary always call to let us know as soon as they receive the result. We can't say enough for Dr. DiBenedetto who really cares about his patients.

Dr. Dibenedetto has been my primary care physician for many years until recently, since I moved away from New York. He is very easy to talk to and very attentive and focused on the patient.
