I have gone to Dr. Gelb since I was 8 years old.... Our entire family has continued to go back to him for many reasons. Him and his staff have always been gentle.
As an adult, I have never had dental insurance, so I cannot say wether or not he is expensive, since I have always had to pay out of pocket, and he is the only dentist I have gone to as an adult, I don't have anything to compare it to....
I would like to add, that I have very sensetive teeth, and I am terrified of getting fillings. Him and his staff have always been kind and understanding, the few times I have had to get them done. I love being able to watch a DVD while I get a filling, it really helps take my mind off of being afraid =)
I'll continue to go to him until he retires (which I tell him he can't!) and I will take my children there when they are old enough as well.
