Patient Comments (4)
in Danbury, CT |
Competent, caring. Takes time to address questions, concerns and procedures to be done, including reasons for the procedure to be done.
in Danbury, CT |
Upon receiving a POSITIVE test result in a Colo-Guard test, I was referred to Dr. O'Brien by my internal medicine physician. I was self medicating, over ten years, for GERD and arthritis pain, using Aleve and Zantac. A stomach ulcer was found during a endoscopy. After his treatment and advice GERD has disappeared. I can now sleep good at night and use Tylenol as needed for arthritis. Dr. O'Brien is very caring and knowledgeable.

This clown has the habit of charging for procedures he hasn't performed. Be warned.
