Dr. Sullivan and his staff are excellent in their field. They are very adept at keeping pain under control. If you want nitrous oxide, you will get it---and without additional cost.
The last filling I had done was by a laser---much better than with a drill.
All of the staff treat you with great dignity, compassion and respect. I have no problems recommending Dr. Sullivan to anyone. In fact, I have recommended him to no fewer than four people over the years. Three of the four have gone to him and are current patients.
