Meet the Doctors
Pediatric dentists have an extra two to three years of specialized training after dental school and are dedicated to the oral health of children from infancy through college years. Infants, young children, pre-teens and teenagers all require different approaches in dealing with their behavior, guiding their oral growth and development, and preventing future dental problems. As trained specialists for children, we are best qualified to meet children's unique needs.
