Eris Martial Arts: Who We Are

Eris is named after the planet orbiting the Sun and has it’s name from the Greek goddess of chaos, strife and discord.

Which is great for two reasons – First, we are one of the original 10th Planet Jiu Jitsu affiliates in the world. Second Jiu Jitsu, at its core tends to be chaotic, full of strife and discord. We teach our students to navigate this effectively and safely – and it transcends the sport and art – students learn to deal with chaotic nature of life.

Eris Martial Arts was established in 2006 by Stewart Landry, and is currently operated by Stewart and business partner Tim Gane. Located in downtown Peterborough and offering training in Brazilian Jiu-Jitsu in both Gi and NoGi for both sport and self-defense.

Why We Are Different



Our instruction has built proven champions, on the provincial, national and international level – all well getting fit and having fun!



Brazilian Jiu Jitsu is one of the safest martial arts, relying on grappling and submission holds as opposed to striking, significantly lowering injury risk.



We switch between the traditional Gi and NoGi weekly, creating better grapplers and martial artists in the process.



Conveniently located in the heart of Downtown Peterborough, on the bus route, perfect for students of Trent or Fleming.

Thank you for all you’ve done with and for her in the last 7 months. I’ve seen her go from a shy girl to a self-confident young lady. She’s setting goals, pushing herself (physically and mentally) and balance her life on and off the mats better. A huge change in her self-esteem!
