Dr. Reagon Noble and Dr. Mason McClintock are certified Diplomates of the American Board of Orthodontics in the Greater San Angelo area! ABO certification requires academic and clinical examination and a profound knowledge and understanding of orthodontics. The board’s mission is to “elevate the standards of the practice of orthodontia; to familiarize the public with its aims and ideals; to protect the public against irresponsible and unqualified practitioners.” Our doctors take pride in providing the highest quality care possible for each and every one of our patients.
