Lecturer for Progressive Orthodontic Seminars from 1994 to present.

In addition to his work with Progressive, Dr. Dana has lectured in Europe, Mexico, Australia, and Latin America on restorative and cosmetic dentistry, focusing on the use of Botulin toxin in dentistry and the use of lip filler for facial aesthetics.

Don McGann, DDS has been contributing to orthodontic research and education for 35 years. He is a leader in his field and has been expanding the boundaries of orthodontics from growth management to appliance design and education.

Dr. McGann graduated from the University Of Pacific Dental School with OKU honors and immediately went into private practice in Laguna Niguel and Santa Ana, California. While attending large amounts of dental continuing education during the 1970’s, he discovered his passion for orthodontics and began a thorough study of the field that has continued to this day.

Initially teaching for the United States Dental Institute (USDI) from 1980-1984, Dr. McGann continued to research orthodontics through exhaustive independent study, attending seminars offered by orthodontists, and practicing thousands of cases in a high volume clinical setting.

This immersion led Dr. McGann to a comprehensive understanding of orthodontics and the most effective methods of teaching ortho to the general dentist. In 1984, Dr. McGann created and began teaching his own orthodontic course, Progressive Orthodontic Seminars (POS). Progressive was designed to streamline the straight-wire type techniques taught in university orthodontic programs, allowing dentists to offer orthodontics to their patients at a standard of care identical to that of orthodontists.

Between editing the GP Ortho News, presenting lectures at the ADA and AGD annual meetings, and the worldwide success of Progressive Orthodontic Seminars, Dr. McGann has established himself as the world’s leader of GP orthodontic education. Dr. McGann holds several orthodontic patents and has been published in the Journal of Clinical Orthodontics, Asian Dentist, GP Ortho News, and numerous other journals.

Additional achievements include:

  • The creation of the Internet Assisted Training program, which allows students to perform the majority of their orthodontic training through the Internet through over 8000 pages of cases, lectures, videos, and exercises.
  • The development of Individual Patient Appliance (IP Appliance), the first customized orthodontic appliance, which accelerates case treatment time and eliminates wire-bending, 2003.
  • He developed the McGann Growth Software in 2013 and continues to innovate in skeletal anchorage, growth research, and growth management analysis.
