Dr . Zadik and his staff are by far the most professional team of dentistry I have ever experienced. The state of the art equipment, the cleanliness, and most important, the knowledgeable staff is exactly what I admire about Dr Zadik’s practice. He himself is not only an exceptional dentist, but an honorable, hard working, leader in his field.
His newly renovated facility is beautiful and parking is easy. I highly recommend Dr.Zadik for not only general dentistry but for caps, crowns, and other issues related to improving your smile and confidence.

Nicest staff. I always leave this office feeling encouraged. Greenwich Dental Group also has the best doctors and the latest knowledge and equipment. They make me feel safe😀

Best dental experience we’ve ever had. My girlfriend needed an urgent last minute procedure and the team at GDG not only squeezed us in within the hour, but they were also so welcoming and helpful in making sure the procedure was done correctly and quickly. Dr. Altman was phenomenal. I will be having all my Greenwich family members switch to GDG - exceptional experience.

The front desk staff, hygienists, and dentists are all great. I feel comfortable here, and the dental care is top notch.

Update: I just came out of the second session of a root canal on a back tooth that required a lot of work. Dr. Altman is the best - he made sure I was totally comfortable the entire time. Best of all, from start to finish both sessions were completely pain free. I can’t recommend Greenwich Dental Group enough.

Dr Altman and his assistant Natalie are so wonderful. He is so kind and comforting especially for a patient like me who is very anxious and sensitive to the drilling noise. They give me a cozy blanket, a ball to squeeze, and a neck pillow. You also get to watch a movie through their headphone/goggles and honestly it’s the nicest set up I’ve ever had. Dr. Altman and Natalie couldn’t be nicer throughout the appointments beginning to end. Every now and then Natalie puts her hand on my arm just to reassure me. He has this trick when giving anesthesia so that it doesn’t even hurt all going in. Most importantly, Dr Altman is a perfectionist! He won’t stop until everything is perfect. Also, he truly cares about his patients well being. He even gives out his personal number after a dental procedure so you can reach him at any time. Even the ladies at the front and back desks are lovely there. I can’t say enough great things about this place!!!

The best dentist in the area. Everyone in the office makes you feel welcome and comfortable, every time visit is a good experience. I think the employees know that most people fear going to the dentist so they make sure you have as pleasant of a time as possible. 10/10 would definitely recommend this dentist office to anyone.

I had an excellent cleaning visit at Greenwich dental group today. Emily took extra care in making my cleaning as smooth and pain-free as possible, and Marc was very thorough and articulate with my examination. They have all of the most advanced tools at their disposal, I could not recommend the more. Thank you again

The staff was wonderful. The dental hygienist Val was gentle, patient and kind with someone (me) who fears going to the dentist. She explained all the steps she was taking and put my mind at ease. The Doctor was equally patient and generous with his time answering all my questions. I would highly recommend this dental practice.

Got appointment promptly. I was treated with concern for my comfort. Was given a detailed diagnosis and instructions for aftercare.
I have recommended thus dental practice to many of my friends and will continue to do so.

A dentist office that feels like a high end Spa. That’s the best way to describe Zadik’s office. Not sure how the entire staff is always so nice but they are all so pleasant. Really makes going to the dentist a joy instead of something to avoid.

Very very easy and positive initial experience. Efficient and thorough and friendly to boot. Val as good a hygienist as there could be, and Dr Altman a top shelf dentist. Could make going to the dentist fun.

The absolute best!! I had been dealing with gum inflammation for years. Valerie and her kind and careful way gave the best cleaning! Almost immediately my inflammation has started to resolve! I really love how friendly and efficient things are here. Starting with the front desk all the way through the entire visit. Everyone goes out of their way to make sure you are taken care of, comfortable, and feel you you might be at the spa rather than the dentist. Very knowledgeable and everything done is of the highest quality. No wonder they are busy everyday of the year! People actually love going to the dentist here!

Samantha did a wonderful job of cleaning my teeth and updating my x-rays. The office has been redone and looks fabulous; plus they have new x-ray equipment. Dr. Altman finished my exam and gave me my fluoride treatment. This practice has the most terrific people; so kind and very skilled! I have been going there for years, and I am always happy to go back.

As always another great experience. Tracy did a very thorough job cleaning, and she noticed a potential problem, Dr Altman made a perfect diagnosis. Knowing I travel 2 hours to see them ( yes two hours. I moved nearly 8 years ago but still use Greenwich Dental. Call me a creature of habit, but why mess with perfection) they offered to treat the problem immediately. I could not stay for the immediate appointment at which point Dr. Zadik jumped in and performed a proactive treatment to tide me over until the new appointment date ( which they rearranged their own schedules to accommodate). Dr. Zadik even called me on my ride home to make sure I was not experiencing any discomfort. All an example of above and beyond service.

I’m a new patient at the Greenwich Dental Group and just after two visits I went from worry and concerns to
joy, optimism and confidence! Dr. Steven Altman gave me that confidence! He is very good, very professional and all in to give you a heathy, shine and beautiful teeth possible! This oficce is high tech and high touch! That was VERY IMPORTANT for me to have the top dentist who is using the newest available tools to achieve the best possible results dentistry has to offer today. Yes this is the place for me!! Their staff is always very helpful and friendly. The office is very beautiful and super clean. I’m so grateful that I saw their business card at my client house and took a step of faith and today I’m so exited and can’t wait for my next appointment! I red that Dr. Altman practice what he believes are the 4 “C”s in dentistry:
Compassion, Courtesy, Competence & Cleanliness and I can say that is 100% what he does!

Dr. Zadik

A great smile is a facelift in everyone’s price range.

David A. Zadik D.D.S.

Dr. David Zadik’s commitment to continuous education and professional excellence began many years ago. After earning his undergraduate degree in his hometown from the University of Toledo in Ohio, he went on to complete his dental graduate work at the University of Detroit Mercy in Michigan, followed by residency programs at both Detroit Mercy and Mt. Sinai hospitals. He then added to his expertise by engaging in rigorous advanced training in the field of restorative cosmetic dentistry. In the years since, he has continued to seek out educational opportunities in new technologies that are transforming dental care and cosmetic options for today’s patients.

I practice what I believe are the 4 C’s in dentistry: Compassion, Courtesy, Competence & Cleanliness.

He is committed to listen carefully to his patients to understand their interests and concerns so that he can collaborate with them to achieve the best possible results dentistry has to offer.

Ultimately, the quality of my dentistry has to speak for itself, but it is also vitally important to me that my patients feel comfort and peace of mind with every visit.

Stephanie Hotchkiss D.D.S.

Dr. Stephanie Hotchkiss is a graduate of the University of Maryland School of Dentistry and completed her residency at University Hospital in Baltimore. Prior to her joining Greenwich Dental Group, she served as director of the Department of Dentistry at Kernan Hospital in Baltimore and director of the Hospital Dentistry Clinic at Bexar County Hospital in San Antonio, Texas.

My mission is to fulfill the needs of each patient that I meet in a personalized and comprehensive manner to restore confidence in their smile and life.
