My visit was very productive. I plan on using Dr. Costanzo as my main Internist for the forseeable future. The entire staff was caring and very helpful. Dr. Costanzo took the time to listen to my medical history which showed me that he truly cared and was invested in helping me.
October 23, 2018Edward K.Verified patient
It was the end of the day and I'm sure he was ready to go home, however he was overly brief. If it was a quick issue it would be understandable, but for a first time appointment and a physical it felt dismissive, uncaring, and a little disrespectful. He made no effort to get to know me and made almost no eye contact. After waiting over an hour in the waiting room and then a short time with the nurse, I was in his presence all of three minutes- five at most.

April 11, 2016Susan C.Verified patient
I couldn't be more pleased with my visit with Dr. Costanzo. I was impressed with the thoroughness of his examination and with his pointed questioning. I left his office feeling that I was in good hands.
I got a good feeling from his staffers who were congenial while being efficient. This is an office that is well run, spotless and pleasant to be in. Everything was planned to make your visit painless, even the parking is close by! I wholeheartedly recommend Dr. Costanzo!
