“Entire staff was so friendly and polite. Doctor listened to my concerns and was able to recommend treatments and explained why they were suggested and why she suggested them in that order. She also had someone check if my insurance would cover specific things while I was being seen to keep things running smoothly. Front desk helped me sign up for care credit for the procedures my insurance doesn't cover. Love them!”

I had been looking for a dentist for a couple of years that I felt comfortable trying after having the same dentist for 11 years and my insurance changing 3 years ago! Dr. Klappas and the staff were AMAZING from the time I entered the office. Truly a wonderful experience and I can’t wait to be back.

The office was spotless and comfortable. The staff was very professional and courteous. The Dr. was very knowledgeable and explained the treatment I needed. Appropriate appointments were made for the treatment, as well as a routine cleaning appointment. My father was a dentist, and my sister was a dental hygienist. I was an investigator for the NYS Department of Health; consequently, I know professionalism when I see it. This was the first visit with Dr. Klappas, and I look forward to being her patient.
