Title:  Certification and Fellowship Training Programs in Addiction Medicine

Presenters from The Addiction Medicine Foundation:

• Tim Brennan, M.D., M.P.H., FASAM -- Vice President for Medical and Academic Affairs
• Andy Danzo -- Director of Fellowship Development     

The Addiction Medicine Committee hosts 3 national experts in physician certification and training in Addiction Medicine. Certification eligibility criteria for Medical Toxicology physicians will be reviewed, as well as the state of fellowship training and the development of new fellowship programs. There will be time for questions and answers and an example of a successful application for the Addiction Medicine Board Exam (from a Medical Toxicologist) will be reviewed.
