Nice office, friendly receptionist, very clean and organized. Dr. Do speaks excellent english, which was a concern of mine based on his name. Dr. Do did an excellent job of explaining the procedure and soothing my anziety over my root canal. The root canal procedure was relatively painless and I was impressed with the efficiency and speed demonstrated by Dr. Do in completing the work. My regular dentist, after seeing the work that Dr. Do had performed, was very impressed with the quality of work. Dr. Do also provided detailed information to my regular dentist, allowing her to more effectively put in the permanent filling and crown after Dr. Do had completed the endodontic work. I had the procedure a couple of weeks ago and would highly recommend Dr. Do for any endodontic procedure.
