"A superior dental experience! I truly feel I’m in good hands when I go to KFA. Everyone is extremely professional and their work is thorough. Great atmosphere, I always feel comfortable. I love the entire staff there... Super friendly and helpful! I wouldn’t go anywhere else!!"



"I started going to KFA Dental around 8 years ago. They are the BEST by far! Everyone in the office is kind, compassionate and professional. My dental Hygenist, Melissa, and my dentist, Dr Aldieri, have taken excellent care of me. They are truly concerned with my overall health, In addition to my dental needs. If you are considering switching, look no further. This is the place to get the absolute best care!"



"I have been going to this dental practice for more than 25 years and couldn't imagine getting dental work done anywhere else. They have moved from their original location and have added 2 dentists over the years but a practice I always loved got even better over time. I cannot say enough positive things about my experience there. The office is modern and immaculate. When you arrive for your appointment, you are immediately greeted by the friendly staff at the reception desk. The office is run like clockwork so you never have to wait very long. Once called in, you are personally escorted to your dental chair (which has a massage option) where they go out their way to make you feel extremely comfortable. You get personalized attention to discuss any problems or concerns you may be having in your mouth. This office has all the latest and greatest in technology to make your experience the best it can be. The dentists, hygienists and all staff members are great people who are very caring and dedicated to their profession. My family of five are all patients and although my older children moved away from the area, they return to have all their dental work done by KFA Dental!"



"The Best dentists around. So caring friendly and excellent results. State of the art equipment. Treated like family. Wouldn’t go anywhere else."



"Our family has been going to this office for years. They have the best staff and dentists that I have ever been to. I look forward to seeing the hygienist Victoria because she always makes me feel so comfortable. Dr Alderi and Dr. Ferrari are AMAZING and I feel like like a good friend instead of a patient they are always professional and friendly. They really try to make you feel comfortable about getting major work done. They explain everything in details and they welcome any and all questions. I love this office and I wouldn’t go anywhere else. I travel from Lake Grove to see them just because they are truly amazing and worth the trip."
