Assistant Jiu Jitsu Coach

"THE HONEY BADGER" started training jiu jitsu in September 2011 and fell in love with it the first day. She is a brown belt under Coach Bryan Brown at 10th Planet Jiu Jitsu Jacksonville. Mattie's attention to detail has made her a great asset to the team, especially as the instructor for the 101 jiu jitsu classes. 

Her love for jiu jitsu is only surpassed by her love for empowering women through self defense. She runs our women's self defense program known as Athena: Women's Self Defense.
