Our Mission at Legion Jiu Jitsu

At Legion our mission is to provide you or your child with everything you need to be successful at the different stages of your jiu jitsu journey.

The environment we created is welcoming both 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.

Secret Sauce Curriculum

Our 10 class curriculum features essential techniques, organized in a way that accelerates learning and removes randomness. Our proprietary system of sparring will get you sweating, but safely.

Start With Other Beginners

Starting jiu jitsu with a group full of more experienced people is not fun. Normally it leads to someone trying to make you their lunch or you just feel out of your depth. At Legion your day 1 starts on the same date.

Get Insane Bonus Perks

Free Legion uniform, lifetime access to class recordings and access to our in-house gym area are just some of the perks that come with the 5-week course.

I love this place.

My family is learning so much. By far the best martial arts gym I’ve ever been to. The staff is incredible and the coaches are so knowledgeable. . . 

Absolutely incredible gym.

Some of the best instructors in the world. They are very welcoming from the moment you walk in. Regardless of skill level this is a good fit for Day 1 beginners or people with years . . .

A unique style.

There is no intimidation walking into this gym. Everyone is smiling, welcoming and willing to guide you. The beginners class in particular is more than you could ask for!.. . .

5 week beginner course.

All the coaches are very clear and detailed on how they teach each technique. I did not think that I would learn this much in such short amount of time. . . .
