I just want to give a big thank you to the team. My little one has been through a rough few months and the entire team showed so much kindness, respect, and patience. We are very grateful 🙏

— LM

I feel very fortunate to have found a wonderful dentist. The team in Massapequa is always very helpful and kind. My daughter has had several cavities filled by Dr. Jeanine and she rocks!

Dr. Jeanine has tons of patience and has a genuinely kind and caring nature about her. She’s is very helpful and knowledgeable. My daughter has never acted concerned to go to the dentist once meeting Dr. Jeanine. There is never a wait time either which is nice too.

— Danielle

I can not say enough wonderful things about the team and the doctors. I was a new patient who called and given my situation, they were able to get me In the same day. The doctor was funny, informative, and was able to keep my child calm while he did the work that was needed.

— Maritza C.

Really great pediatric dentist! My 5 year old loves going there and loves how the office is decorated. My 3 year old is not exactly happy going to the dentist but the dentist makes me feel at ease even when she’s throwing a tantrum. Highly recommend!

— EM

The staff (doctors, hygienists, office)is absolutely amazing. Everyone helped put my daughters mind at ease. The use of lasers to fill cavities makes the process quicker, painless, and shot less. The office staff is pleasant and accommodating. I would highly recommend this office. We love Dr. Adam and Dr. Bennett

— Sara

Dr. Bennett was great! He took his time to answer any questions and was very kind and laid back with a first time dentist appointment

— Tom R.

Dr Mark is an excellent dentist who is in a league that his competition can only strive for. From the moment you walk into the practice you immediately see what sets him apart from all the other pediatric dentists in the area. The front desk staff are pleasant ,friendly, and professional. The office has an ocean theme which feels inviting to kids when they walk in along with the video game wall and the interactive play tables. The practice utilizes the latest cutting edge technology. I particularly like the use of the laser instead of the drill which enables the dentist to maintain the integrity of the tooth way better than the drill would. The entire staff is amazing. I have been bringing my daughter to this practice for over 10 years and she has beautiful teeth. If you are looking for a dentist that values their patients and does outstanding dental work then look no further.

— Laura

Dr. Bennet was excellent! We brought our 6 week old in for a tongue/lip tie evaluation. Dr. Bennet took the time to address our concerns and made us feel very comfortable and informed. It was clear he really cares for each patient. We would recommend him and his team to anyone!

— Shelly M.

Wow! What a wonderful experience. Everyone, especially Dr Bennett made me feel like I was at home and not at an appointment for a procedure for my newborn. He was so lighthearted and explained everything very thoroughly but with patience and humor. My son got his tongue, tie and lip ties removed today and I am looking forward to all the progress he’s going to make! Thank you thank you!
