The Edward H. Angle Society of Orthodontists (EHASO) grew out of a distinguished Angle School alumni organization begun in 1922. The members were dedicated to Dr. Angle’s goals of excellence and progress in the art and science of orthodontics. In 1930, The Angle Orthodontist was inaugurated by the Angle Society as a means of furthering these aims.

Today, EHASO is a global society which adheres to its founding traditions. Membership, drawn from the entire community of orthodontists, consists of men and women identified as able and willing contributors to the advancement of orthodontics. Orthodontists with these qualities are invited into the membership process at the regional Component level.

The Angle Society presently has over 660 members (approximately five percent of North American orthodontists and more than 70 orthodontists from countries outside North America), distributed in seven Component Societies. Each Component meets regularly for scientific sessions and for fellowship. The seven Components convene every other year for an International Biennial meeting, providing an opportunity for the entire membership to study and discuss some of the most important orthodontic advances from that period.
