Dr. Bob has done a wonderful job in introducing my daughter and nephew to dental care and health in a positive, exciting way. We've been going for 3 years, since she was 3. The introductions, explanations, and staff are perfect for small anxious children and their more-anxious parents. The technology is the latest . Dr. Bob also does great work with disabled children. The office is filled with toy trains. The waiting room is a playroom paradise. So far we've only had preventative care. Hopefully thats all we'll ever need! I don't know about comparative costs. I like Dr.Bob so much, I never considered anyone else for my child.
