I hadn’t been to the dentist since before Covid and was very nervous. Dr. Kholdarov was fantastic and the whole office staff was great. Would definitely recommend to anyone looking for a dentist in the area!
October 27, 2021Angela K.Verified patient
The reviews are what led to my choosing this practice and they delivered. Everyone in the practice was friendly, informative, helpful and effective. I was particularly pleased that the doctor is truly hands-on, doing the cleaning himself rather than delegating. They also have great technology to view images of your teeth in real-time. I didn’t leave with any discomfort nor pain.

Having new insurance due to a job change and my old dentist being in Manhattan, I decided to find a local dentist and couldn't be happier with my experience here!
May 2, 2021Emily E.Verified patient
Hands down the BEST dentist I have ever had. I have been a patient now for over 3 years and I don't ever want to have to change. The entire staff is also super professional and friendly.
April 8, 2021Viviana R.Verified patient
Super friendly staff, good listeners and gave great advice. Very compassionate about how things might be uncomfortable and checked in with me to make sure I was okay, also fine taking a pause as needed. Were open and honest about any concerns and good at explaining it clearly. Also brought up the cost as soon as I asked about insurance.
Everyone I saw was so kind, and caring. I felt heard, and respected, as well as reassured for any concerns.
So happy to have found a good dentist!

The staff could not have been more friendly and it was a great experience. I had Michelle as a hygienist who was very complimentary and friendly. The only hiccup was that the office's scheduling does not seem to be aligned with ZocDoc's, so they initially thought I was a no-show/was 30 minutes late but they were very flexible in accommodating the mix up.
