Dr. Terry Geller - Dental Director of the Geller Family Dental practice

I Graduated from New York University College of Dentistry in 1976 at which time I started Geller Family Dental, which opened in its present location at that time and has been treating patients in the community for the past 36 years.

Having my children practice with me is a fulfillment of a long time dream, and they will secure this practices future in the community. We now treat the children, grandchildren, and great-grandchildren of the original families I started treating.

Over the years I have always provided comprehensive treatment for our patients, caring for all of their dental needs. At this time I focus most of my time in the practice placing implants, and doing major reconstruction cases. I also perform Botox, and dermal filler procedures.

My wife Michele and I are involved with New York Presbyterian Hospital, as well as Hospice and Palliative care of Westchester.
