Dr. Marvin Kastrop of Billings has completed his term as president of the American Board of Orthodontics (ABO), the only orthodontic specialty board recognized by the American Dental Association and sponsored by the American Association of Orthodontists (AAO). Board certification is a process by which an individual orthodontist is voluntarily examined by his/her peers as to orthodontic knowledge and clinical skills. Each ABO director represents one of the eight constituent organizations of the AAO and serves an eight-year term, which culminates in the position of the president. The ABO directors are responsible for establishing policy with regard to the board certification of specialists in orthodontics. During his tenure as an ABO director, Kastrop represented the Rocky Mountain Society of Orthodontists (RMSO).
Kastrop earned his DDS from the Baylor College of Dentistry in 1968 and pursued his postdoctoral education in orthodontics at The University of Texas Dental Branch at Houston (UTDB). He earned his master’s degree from UTDB in 1973. Kastrop has maintained a private orthodontic practice in Billings since 1973. He is a fellow of the American College of Dentists, a diplomate of the ABO and a member of the College of Diplomates of the American Board of Orthodontics, the AAO, the RMSO, the Montana State Orthodontic Society, the Ninth District Dental Society and the Angle Southwest Component of the Edward H. Angle Society of Orthodontists, among other organizations. He is a past president of the RMSO, the Montana State Orthodontic Society and the Ninth District Dental Society.
