“I’vy been a patient with Dr Troy for fifteen years and have always been impressed with him and his entire staff. I am 86 years old and was hesitant to make my visit, but his whole staff used the best practices to insure the safety in the office. Unfortunately , I will be moving to California ima month or so and will have to find a new dentist , and hope that they will be as good as Dr Thomas and his staff.”

“Dr. Nguyen and the dental hygienists are super nice! I felt comfortable and safe—even the time I started crying when I had a panic attack before getting some cavities filled. (Sorry about that lol.) Anyways, Dr. Nguyen was very kind, gave me space to chill out, and didn’t make me feel embarrassed, even though I wouldn’t have blamed him if he did.”
