Cannot say enough amazing things about Dr. D'Agate. Always nervous seeing a new physician, especially one found online and not refered to me by someone I trust, but Dr. D'Agate was incredible from the minute he opened the door to theexam room. Came in with a big smile and hello, shook my hand and introduced himself. Having obviously taken the time to read through my chart before coming into the room based on the knowledge he had regarding my medical history (which I feel many physician's do not take the time to do), he proceded to sit down and have an honest, organic conversation with me; getting to know me as a person, about my symptoms, what could be causing them, what he wants to do as far as testing and treatment plans, if required. I can tell you that I've seen many doctors over the last year or so, and this was by far one of the most calming and comforting experiences I've had to date. I left that office knowing I was in fantastic hands. Already recommended that office and Dr. D'Agate to two other people!

My husband and I have been seeing Dr. D'Agate for several years. Not only is he an excellent Cardiologist, but his bedside manner is AWESOME! He's a compassionate, caring Doctor. He immediately makes you feel relaxed when he converses with youduring an office visit. If it wasn't for him and the tests he ordered, I would not have known that I had a blockage which could have resulted with a serious complication. I am thankful every day that he is my Cardiologist!

Pleased with the doctor and the form of treatment he is recommending. The wait time was long, especially since our appointment originally was at 11:30 and they called to ask us to come in earlier, at 11:00am..which we did. Then waitedin the waiting room for over an hour and a half. Also, I filled out all the forms on ZocDoc to save us time and they made me fill out there forms.

I had a very positive experience with Dr. D'Agate. He is a very friendly, professional, efficient Dr. My only concern, was the number of things he was scheduling me to do, was a little overwhelming. But at least it felt likehe was doing everything possible to help me. I feel as though I am in very good hands.

All staff were very professional and courteous. My only criticism is that there apparently was confusion about which office location was responsible to input the ZocDoc appointments into the appointment calendar. That resulted in my medicalrecords being in their computer, but not my appointment. The resulting delay was relatively short, but mildly disconcerting.
