Dr Andrew is a member of a select worldwide group (of approximately 50 dentists) which are collectively called TMJ & Sleep International. Some of these centres, due to their advanced knowledge of the jaw are contracted to make mouthguards for high performing teams in the NFL such as the New Orlean Saints, in the NBA such as the New Orlean Pelicans and for college football NCAA teams such as Notre Dame and USC. After introducing these mouthguards at Notre Dame, injuries immediately dropped by over 60% in the new freshman year.
