I wonder if some of the other positive reviews were written by the dentist herself.Anyway, I am very unhappy with Dr. Gress. I have been going to her for a little over 3 years as my son lives near her office, and she is convenient. Over time I have grown to like her less and less and trust her less and less. I feel that she only cares about the money, and I feel strongly that she overcharged on more than I occasion.Dr. Gress also treats her workers like slaves. Last time I asked for the explanation of a bill and she started screaming at me and talking down to me . Never again, there are too many good dentists on Long Island.If you value your teeth and your self respect stay away from Nancy Gress D.D.S.and Progressive Dentistry .
