JIU JITSU

BRYAN BROWN "COACH B. BROWN" is a black belt under 10th Planet founder Eddie Bravo, and has been training with Eddie since 2006! He started at the Bomb Squad when it was the only 10th Planet, which now has over 80 Moons orbiting around the 10th Planet HQ in Los Angeles. One of Bryan's goals has been to become the head instructor of his own Moon. His heart lies in creating the best atmosphere, training partners, and best instruction in our community. 

In 2017 he married the love of his life, Mattie Brown. Outside of his life of jiu jitsu, Coach Bryan has quite the musical talent. 

​

MATTIE BROWN "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.
