Coach Mathis is married to his beautiful wife, Megan, whom he’s been married to for over a year now. They enjoy trying new restaurants, going on hikes, movie dates, and playing volleyball.

His goal as an educator and coach is to teach students and athletes that every decision they make affects more than just themselves. They have an effect on those around them, and what they choose to do is more important than they think. Coach Mathis wants them to understand that their decisions and habits make all the difference in their sports, classes, and lives. His coaching philosophy is to instill confidence in players, whether that’s on the field, court, class, or in society, so they choose to do something positive no matter what life throws at them.
