A Message from the President – Dr. Eric Dellinger

Dr-Eric-DellingerThe founding of the College in 1979 began as an attempt to increase the number of board certified orthodontists, and we are proud to continue this legacy with our 41st annual session in Nashville. The College quickly grew beyond simple mentorship, by providing classes to give aspiring orthodontists the tools to understand and pass the American Board of Orthodontics examination. The College continues to provide the finest education available to achieve board certification, but also provides the world’s finest orthodontic study club by virtue of its annual meetings. 

The annual meeting in Nashville will once again provide the opportunity to learn and share with the world’s best orthodontists in a very personal study club atmosphere. The harmony of Nashville’s music city will provide the backdrop for our meeting theme of “Harmony in Orthodontics.” My wife Katie, myself, and our entire family hope to see you and your family at the  40th anniversary of the founding of the College of Diplomates of the American Board of Orthodontics in Nashville, for fellowship, fun, food, music, and exceptional education!



To promote and support the pursuit of enhanced quality of care through the process of ABO certification, re‐certification, and continuing education.
