Meet Our Associates
Our doctors and staff work together as “family” team members with one goal in mind – to make every child’s dental experience positive and enjoyable. Child psychology is a common second degree in addition to their Doctor of Dental Surgery and Specialist in Pediatric Dentistry or Specialist in Orthodontics degrees. Understanding the child patient is critical to successfully treating their dental conditions, as well as making their office experience enjoyable and rewarding. We are parents ourselves and we are specialists in helping kids smile.
