"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!"



"Root canals are nasty business. If you need one, it must be done, otherwise you will lose the tooth. Over the past two years I have had nothing but horrific experiences with dishonest, incompetent dentists. When I came to Dr. Lewis, I was expecting more of the same. Instead, I found Dr. Lewis to be incredibly professional. It was undeniably obvious she knew what she was doing. She worked with the precision of a neurosurgeon. Now, I am not an easy patient to work with. My mouth does not open very wide, so there were certain instruments she couldn’t get into my mouth, yet she worked around this with relative ease. Dr. Lewis is the Gold Standard for what all dentists should be. I left her office pain free. Now, if only I could find a regular dentist as good as Dr. Lewis, I would be set."



"Dr. Ferrari, Christine, Briana and the rest of the KFA team have been extremely wonderful to work with. They have incredible bedside manor, superior understanding of patients needs, payment flexibility and a wide array of industry knowledge second to none. I have worked through numerous procedures with them from cleanings, to root canal, crowns, and wisdom teeth extractions. The experience has been wonderful and the team prides themselves on the highest level or professionalism. They utilize the latest and greatest technology, are local to anyone in the Long Island area, and really go the extra mile to ensure your smile and experience are both just as perfect. 5 Stars highly recommend."
