Dr. Mark is clearly the best dentist I've ever had so thorough and detailed! I am very pleased with the Treatment I've received at this office. The Staff is always very friendly and helpful I have always been seen promptly upon my arrival. He has everything you want a dentist to be like and very concerned for my comfort in his chair. I heard about him based on a friend's recommendation. My previous dentist never provided as much comfort as Dr. Mark has. I was in no kind of Pain or discomfort During the Preparation for My Crown fitting. He Performed restorative work and did an outstanding job. People are always giving me compliments on how beautiful my teeth look. I would recommend Dr. Mark to anyone who's looking for a great dentist.
