I am a total scaredy-cat when it comes to dentists. All my concerns and worries were taken care of by Dr. Chen. She was awesome. Her bedside manner was just the best and really made me feel at ease. Her workmanship was impeccable and I am 24 hrs past my root canal- pain free. Just can’t say enough about Dr. Chen.

Dr. Mastroianni and his team are fantastic! I went to their office in severe pain and they addressed it immediately. The technology they used to find the route of the problem was like anything I have seen before. He was able to quickly find the issue and direct me to resolution. I would recommend 10/10!

I was referred to One Endo to detect and treat the source of severe tooth pain. Dr. Mastroianni quickly determined the source of the pain, took the time to explain the problem and the options for treatment, and performed an emergency root canal immediately. I highly recommend One Endo - and in particular Dr. Mastroianni.
