Hospitable Office

Our goal is to provide the best dental care in a professional and caring environment. Our trained and attentive staff make each patient feel comfortable and relaxed. There is minimal waiting time through accurate scheduling and efficiency.


Each room is sterilized and all the plastic covers are changed after each patient. Among all of us we speak Spanish, French, Italian, Portuguese, Persian and Hebrew. Our patients are part of our "extended family".


Four-handed Dentistry

Dr. Heller and his staff are experts in the highly efficient movement conservation method of four-handed dentistry - working closely with a trained assistant - facilitating a smoother patient experience. And by combining teeth cleaning with exams, Dr. Heller is able to make a more thorough assessment, saving time for patients.

Athletic Care

Serving as the official dentist for the New York Mets for six years, Dr. Heller has extensive experience with sports issues, prevention, injuries, and emergency treatment.

"I don’t know how to thank you enough for opening your office to meet me and my son after he got hit on the mouth playing hockey. We were all freaking out when it happened and there are no words to express your kindness, caring nature and expertise in all you do." - Wendy

“As a dentist myself

... I know what good dental care is all about. Dr. Heller has been my dentist for over 34 years. You deserve the excellent service and professional care he provides."
– Dr. SRF

“I want to thank you

... so much for always taking excellent care of my teeth. It took me a long time to feel comfortable visiting a dentist until I met you. Someone recommended you to me ten years ago and I have been coming to you ever since. I have been very satisfied and extremely happy with everything you have done for me."
- Ingrid

“Thank you for making time

... to see me on Saturday. I know it was a last minute appointment and that we went back and forth to find a time. I really appreciate your accommodating me, particularly because of my chipped tooth."
