The Greenwich Dental Group is the most incredible dentist office I’ve been to. The staff is so calming, welcoming and gentle. Dr. Altman is fantastic with his thorough exam, and knowledgeable and calming delivery (which is so important for a nervous person like me!). And his staff of front desk folks and hygienists are at the top of their game. Both Christina and Emily worked on my X-rays, full mouth scan (so cool!) and thorough cleaning. They are both so personable and self-proclaimed perfectionists (and I agree!). I was actually having a fun time in the dentists chair, which usually not the case with other practices I’ve been to. Wonderful welcome to the Greenwich Dental Group family!

If you have to go to the dentist(which we all do) then I highly recommend Greenwich Dental. Dr. Altman’s office runs like a Swiss watch. I’ve never had to wait on an appointment and his staff are very professional and friendly. Tracy Springer, RDS does my cleanings and she is excellent. They are the gold standard!

I strongly endorse Greenwich Dental. I had an excellent experience with Silvia for a cleaning and exam with Dr. Marc Novak. This is an exceptional team and I’m grateful to have found them. I look forward to my next appointment with them - never thought I’d say that about a dental practice! Keep up the good work!
Dr. Altman went above and beyond to make sure I understood all my options before moving forward with any procedure. He is very knowledgeable, patient, and always ready to help. All team is just unbelievable. Extremely professional and helpful.
I ended up doing implants, veneers and Invisalign at Greenwich Dental Group and couldn’t be happier with the results. Look like brand new man 20 years younger.
Excellent job 👍

Dr. Marc Novak was awesome!!! I chipped my tooth last night and he was immediately responsive when I reached out at ~9pm and he squeezed me in this morning before his scheduled patients arrived. I had big meetings today so it was really helpful that he got my tooth fixed so quickly!! I’ll definitely be recommending this practice going fwd!!

I was visiting Greenwich last week with family when my lower bridge unexpectedly came out of my mouth. I was panicked and embarrassed. I was staying with my cousin who assured me that his dentist was "The Man" and he would fix me right up. I was worried that he could not fit me into his schedule and help out a non-patient that he did not know on such short notice. "You don't know Dr. Zadik" my cousin told me. He will "hook you up." My cousin called Dr. Zadik's office and they literally rearranged their schedule to get me in. When I arrived I immediately realized I was in the right place. Within 15 minutes, Dr. Zadik had me chomping again and returned my smile (and confidence) back to where it had been. I am not only thankful to this wonderful man, but I am truly grateful. Good man. Great dentist. He stepped in. Stepped up. Fixed me up. And sent me on my way along with his cell phone number in case it popped out again while I was in Greenwich. Now, that is how you care for people. Thank you Doctor Zadik!

I moved to NYC but continue to come out to Greenwich to see Dr. Altman and Dr. Zadik.

Their team is impossibly nice, their offices are clean, comfortable and modern, and their bedside manner is top notch. I would absolutely recommend them to anyone looking for dental work, no matter how big or small the procedure!

Many, many thanks to the amazing Greenwich Dental Group for my recent visit when Dr. Altman replaced a crown within three hours of having fallen out!
Everyone I have recommend to this practice
has had nothing but raves about their
experience. A friend whom I recommended
recently proclaimed Dr. Zadik a rock star!
The only problem they have with me is
trying to keep me awake because the entire experience is so relaxing that I take a nap!!!

Dr Altman and his team were amazing, very impressed! My 10 yo son chipped his tooth and the office made sure Dr Altman saw him immediately, as our dentist was on vacation. Everyone took great care of us as a new patient. I will be switching to Dr Altman, after the experience we had today! I highly recommend the office, Dr Altman is great with kids, and his work was excellent!!

I recently had a teeth cleaning and exam by Tracy. She was so thorough and genuinely cares about the health of your teeth and offers great suggestions in keeping them at their best possible condition. It was the best cleaning I ever had. Thank you so much, Tracy!
