    Meet the staff.
    Alan A.

    I have been using Dr. Zaffos since he first hung up his shingle. He is a compassionate and caring doctor who has always been there for me and my family. Weather it's a basic check-up and cleaning or an emergency Dr. Z will be there for you. Through the years I have seen Dr. Z go from your basic family dentist to a cosmetic dentist who teaches other dentists how to do it. He has a staff of professionals who will treat you like family and give you the type of service you'd expect from an office that's been in business over 20 years. If you visit Dr. Z tell him Alan A. says hello!

    Dr. Zaffos grinded denture down so much you can see through 1 side. Denture is full of reline & causing excruciating pain

    I'm very dissatisfied with Dr. Zaffos' work. It took Dr. Zaffos 8 months to make me dentures that he promised to make in 2 months. 2 times he made wrong fitting & poor quality dentures. My mouth has been bruised & sore for 8 months. I kept going back to him on a weekly basis because of all the pain I was in from the inadequate dentures that he made & now he's refusing to correct his mistakes & refusing to refund $2000 that I paid him & I'm still in pain. The 1st denture that he made was lopsided & the 2nd denture that his daughter designed was way too big for my mouth so he kept relining it. He grinded it down so many times you can see through one side of it now. I showed it to 3 other dentists & they all agreed that this is substandard work & the denture has to be completely rebuilt. Through no fault of mine, Dr. Zaffos caused me excruciating pain & suffering for 8 months & he is now refusing to correct his mistakes, by remaking proper fitting dentures & he's refusing to refund me $2000. I complained to him in an email. He never addressed my complaint, not in writing, nor in person although I went back to his office for so many more adjustments. Dr. Zaffos seemed very pleasant at first but he does substandard work & he showed his insensitivity & arrogance by ignoring my complaints & refusing to issue me a refund.

    Beautiful and clean....

Dr. Pacinelli is a personable, skilled, and attentive doctor who has the knowledge and skill set to address the specific dental needs of his patients. In my case, I required a partial denture, which was something I never had before, and I was very concerned about comfort and the aesthetics to regain my smile. On all counts, Dr. Pancelli was able to fabricate a partial denture that met my requirements. I left happy and smiling once more. I highly recommend the practice.. Lucia A.

    My issue was my lower implant 4 screws came out (implants done in 1997) in Florida. Went to…read moredentist in West Setauket and he gave me a story about not having proper equipment to put screws back. And new implants for lower/upper would cost me $40,000. Cost me over $700 just for X-rays. The second Dental (Pure Dental, Manorville) did another set of X-rays and was honest with me and said they also don't have tools to add or remove the type of screws I have. However, he gave me referral of a Dentist who would be able to help me. DR. ANDREW PACINELLI. When I got home I called and made appointment, the woman was helpful when I explained what I needed and said yes he can help you. He was EXCELLENT, POLITE, UNDERSTANDING! And was able to help me. What a God scent! I would recommend him to everyone whether you had implants 28 yrs old or 1 year old. Or want implants done.

This man is the best - he and his staff are fantastic with this patient that is deathly afraid of dentists from a traumatic experience when I was 5. His work is beyond reproach! The extensive work done in my mouth was not only stress free and painless, it was done in a very welcoming and relaxing office environment! AnnMarie, the office manager is awesome - from the first contact, you feel like you are speaking to someone you have know for years! She is comforting, welcoming and just simply fantastic. Ginny is a godsend! She is calming and nurturing with a beautiful smile! Her presence at your side assisting the doctor is pretty much all you need to feel safe and taken care of while Dr. Gardner does his work! Perfectionist is what he is - you cannot be happy with his work if he is not! He is absolutely the best dentist on the North Shore! He and his wonderful staff will make sure you are comfortable - All Dental gumbies need a Dr. David Gardner and anyone looking for a great dentist should use him too. I am thankful for them all! My teeth look GREAT and the proof is in the compliments I receive each day!!thank you Dr. Gardner, Annemarie and Ginny for all that you have done! I love my implants!!!

I arrived on time filled out info on an ipad And was taken within 15 min. The tech very pleasant,the doctor Dr. Singh very friendly and understanding explained everything and approximately the time is would take. At that point i decided to have a new denture for the top. As I waited for the repair Devin (ops manager) went over aĺl the costs and the final bill. All I can say is thank you to my old dentist. I was so pleased. I am in retail and no what customer service is and this Aspon has it! I am returning to start my fitting for upper dentures. This appt Thursday July 18 2025

We were 10 minutes late. The receptionist told us the dentist had to leave by 1 PM . This was our first time at this office and we would be a new patient. According to the notes of the person who made our appointment we were told to be at the office by 12 noon because the dentist had to leave at 1 PM. I do not recall being told we had to be there by 12 PM. We received multiple text messages stating our appointment time with no mention of the doctor leaving early or arrive early to fill out the required forms so we could start on time. So we did not see the dentist. Oddly enough there was another client who arrived at the same time as we did for work on a crown. He was an established patient and was seen. We were told to reschedule. I said no because we hired ambulete to get my sister there as she can not stand. I was told this office had a hoyer lift to help her get in the dentist chair comfortably. I might add this was the only office that uses the hoyer lift in Nassau and Sufolk that uses the device. My complaint is simple why did the scheduler who made this appointment not call us back to reschedule when she knew the doctor had to leave early? Also if you needed work on a crown what are the odds the job would be done in 20 minutes! I have to say this is poor office management. We found a dentist who will visit my sister at her assitant living facility. Michael J

I am grateful to you and your amazing staff who went out of their way to make me always feel comfortable and welcomed. The process was so smooth and your patience and thoughtfulness in answering my questions along the way was very much appreciated. BTW, I love the dental chairs in your office, which are even more comfortable than my bed at home! And the cable TV/NETFLIX were icing on the cake. It was a hands down FIVE STAR experience. Considering I travel from NJ to your office (a 90 minute drive), why would anyone living on Long Island have their teeth cared for by anyone but you?? I may retire on Long Island just to be closer.
