Mission Statement

At Legion our mission is to provide you or your child with world-class jiu jitsu instruction. 

We want to do so in an environment that’s welcoming for those who are hardened warriors and those that are trying jiu jitsu for the first time. Our members come from all walks of life, from ages of 4 to 65+.

We realize that starting jiu jitsu as a complete beginner can be daunting. That’s why we pioneered our 5-Week Beginner Course, which comes with a guarantee that you will start alongside other beginners. 

Why should Legion HQ be the place where you finally try jiu jitsu?

How are our memberships different?

There are no signup fees at Legion.

Legion wants to let you know you get access to all online content with your membershp.

Access to Online Courses

We’re big believers in using the medium of video to advance jiu jitsu learning. Even with perfect focus and memory, you can only learn so much on the mats. That’s why we include access to countless hours of online courses with all adult memberships. Valued at over $500, but included for free. (Thanks to
