Welcome to Atos Jiu-Jitsu Hamilton! We have been servicing Hamilton, ON and many surrounding areas such as Ancaster, Stoney Creek, Burlington and Brantford since 2009. At Atos Jiu Jitsu Hamilton, we are led by a team of fantastic instructors, who follow the teachings of multi-time World Brazilian Jiu-Jitsu Champions Rafael and Guilherme Mendes. The Mendes Brothers are responsible for creating a style of Jiu-Jitsu that has become known worldwide as “modern Jiu-Jitsu.” They continually create, develop and innovate techniques that have helped them to win multiple world titles. If you are looking to stay at the cutting edge of proven techniques and concepts, then look no further than Atos Jiu Jitsu Hamilton. We take great pride in following a structured BJJ system that focuses on your development while continually monitoring your progress. 

We have BJJ classes for everyone of all skill levels, as well as for ages as young as 6 and up! Brazilian Jiu-Jitsu is a contact sport and we provide a challenging yet safe environment for your child to mature into becoming a real-life champion on and off the mats. The discipline, focus and hard work expected by our instructors often carries over to the child’s behaviour at home and at school!
