OUR MISSION

To deliver world-class Jiu Jitsu in a safe, positive, structured, and goal-oriented environment that imparts members with a comprehensive understanding of technique and situational awareness.

CLASSES

  • Kids learn basic techniques and drills which are masked as fun games and exercises. Class focuses on developing balance and coordination, the importance of giving effort and respecting others, and identifying that there are both proper and improper times and situations for using martial arts.

  • In Big Kids class, students learn comprehensive techniques and practice with partners during supervised sparring rounds. Class structure is similar to adult class: warm-ups, instruction/technique and drilling, and live rolling/sparring. Experienced students are welcome to attend adult classes.

  • Learn the fundamental movements that build the foundation of Jiu Jitsu techniques. Recommended for all students, especially those new to Jiu-Jitsu.

  • Learn and refine submission grappling techniques and takedowns without the gi in fast-paced rolling sessions.

  • Students are assigned a starting position and spar with defined parameters and specific reset points. Positions are explored with greater detail than in standard grappling rounds.

  • Students learn advanced techniques, string techniques together to form complex sequences, revisit fundamental techniques and expand upon them with greater detail, and refine their skills.
