Very thorough and spent the time talking through everything so I felt confident leaving with a good plan of action.

Excellent, Hero in my book!! Most astute physician that I've met with in a long time. Spotted a very serious health problem outside his operating sphere, with an intense line of questioning, due to caring about his patient, which resulted in spawning a procedure that prolonged my life.

It was my second time getting my colonoscopy at the Stamford location. The main office is in Greenwich Connecticut, and I am a new patient to Dr. Anthony. I greatly appreciated his calm and straight forward disposition. He explained the proceedure, process and the steps that I'd need to take for a successful procedure very well. I feel very comfortable with him and I'm pretty picky with doctors. Eventhough I no longer live in Darien Ct, I choose to drive from Guilford Ct to see my current Doctors of 10 years for my yearly check ups. I'm happy that Dr. Antony is my new Doctor, I can tell that he's a great professional. Niki T Fogle-Jonsson
