I have been seeing Dr. Greenstein for over 6 yrs now and would highly recommend him. The office staff is nice and Dr. Greenstein always has a kind and friendly chair side manner that puts me at ease. Both of my children look forward to going to the dentist because everyone is so nice. Maria takes care of the billing and works wonderfully with the insurance companies. If there is ever a problem I just have to call her and she takes care of the matter.
