The Charles H. Tweed International Foundation for Orthodontic Research and Education sponsors continuing education experiences each year. Six Tweed Study Courses per year keep Dr. Vaden, the Course Director, and the instructing staff very busy. The biennial meeting every two years is truly an international orthodontic "happening." Our newsletters are widely disseminated. You will find links to all of the activities—plus a wealth of information about us—at this website. Browse and enjoy!!
