As someone with dentist anxiety, the staff made me feel incredibly comfortable and at ease. They answered all my questions and explained it in a way I could easily understand.

Had a root canal done today. Like they said, it's similar to getting a filling, but takes longer. No pain, and they were reassuring and professional!
