Dr. Novak and his staff are fantastic! They make you feel comfortable and are very warm and friendly! Sara is a wonderful person with a lovely smile and was very accomodating when I asked for particular scheduling times and date. I see the doctor in the Wantagh office and I am very comfortable with everyone working there.
