“This is the best dentist I ever had the chance to get treated by since moving to New York.
Dentist DeBonis spent a whole hour with me on my first visit to learn about me, ensure I understand the importance of flossing (I started taking this seriously now!).
Not only that but he’s extremely meticulous and caring. He absolutely wanted me to come back 2 weeks later (free of charge) to ensure my teeth are in good condition and make sure I’m flossing!
His staff is wonderful. It’s the first time I feel treated like a human at a dentist.
Oh and there’s sweet classical music in the office too ??”

Dr. DeBonis was extremely kind and attentive. I appreciate that both him and his assistant work masks during my visit. Dr. DeBonis took the time to explain things to me, was very encouraging, and made me feel very comfortable. I walked out of that office was clean teeth and a big smile on my face. I would definitely recommend Dr. DeBonis to my friends and family!

Dr. Debonis was very gentle, knowledgeable and comforting during my visit. I have a fear of going to the dentist and he may me feel relaxed and comfortable. He also told me some things I didn't know about proper oral hygiene. I would highly recommend him!

Dr. DeBonis and all the staff were incredibly nice and I was seen quickly. Dr. DeBonis explained everything he was doing and gave good pointers for brushing/flossing. 10/10 experience.

Dr. DeBonis was super knowledgeable and treated the pain I had in my mouth in a very thorough manner (looked at my x-rays for a while, talked me through his hypotheses, asked me more questions about it, etc.). Usually I get an assistant or hygienist when I go for a cleaning but Dr.DeBonis did the whole thing with me (he noted he does this only the first time for a new client). We was very warm and open to answering all of my questions. No complaints!

A fantastic experience all around. Thank you so much, Dr. DeBonis, for your excellent humor, friendliness, as well as THE clearest explanations I've ever received about dental health. You even managed to get me excited about flossing. Lovely office staff, as well. A+
Hope you all stay well! Looking forward to going back.

I refuse to see any dentist other than Dr. DeBonis. His staff is also exceptional - always on time, my comfort is always a priority and everyone takes time to explain what they’re doing in detail as well answer every question I have. By far, one of the best dentists and practices I’ve ever seen.

Excellent. I've been a patient of Dr DeBonis for many years. He has always provided excellent dental care and is a friendly, caring doctor. The hygienists and office staff hav always been friendly, competent, and efficient.
October 19, 2021Chris B.Verified patient
I have been going to this dental practice for many years, and at almost every visit there has been almost complete turnover of the hygienicists and dentists, except for Dr. DeBonis. My care has been good, but the high turnover of staff raises concerns.

June 1, 2021Corey S.Verified patient
Dr. DeBonis has been my dentist for more than twenty years. I have had dental insurance that whole time, but unfortunately it is not accepted by Worldwide Dental. Nevertheless, I am so pleased with my treatment here that I would rather spend my own funds instead of going somewhere else where my insurance is accepted -- and I can't think of a stronger endorsement than that.
May 13, 2021Francis S.Verified patient
I've had to go to quite a few dentists in the past. What I value most are excellent technical skills...the "touch", and a great communicator. For me Dr. DeBonis ranks among the very best.

This was the best Dental practice I’ve ever been to. The staff was very cautious with Coronavirus protocols, and clear to outline their procedures. The technician was friendly, talkative, informative, and efficient. Dr. Debonis did an incredible job at informing me of tips, tricks, and techniques for ensuring good dental health. The doctor even walked me through each X-ray photo to explain what we were seeing and was keen to point out any areas of concern he had. I will be returning to Dr. Debonis for as long as I can, everyone in the office was exceptionally friendly and I highly recommend it to anyone looking for a new practice.

I was very impressed with Dr. DeBenois' attentiveness and thoroughness. He explained in detail the procedure as well as his recommendations. I have never had a dentist be as informative. I greatly appreciate the time he took with me. It is obvious he is invested in his profession and patients. The office staff were very friendly. The COVID cleaning protocols were above many standards I have seen.
