What drives us
Our Mission
At Niagara BJJ Dunnville, our mission is to build stronger, more confident individuals through Brazilian Jiu-Jitsu. We believe martial arts is about more than learning to fight — it’s about developing discipline, respect, resilience, and the confidence to face life’s challenges.
We strive to create a welcoming, supportive community where students of all ages can challenge themselves, overcome obstacles, and grow both on and off the mats.
Our goal is simple: to build better Jiu-Jitsu practitioners, stronger individuals, and a better community — one class at a time.
The people behind the mats

James Chandler

James is a first-degree Brazilian Jiu-Jitsu black belt with 17 years of BJJ experience and 25 years of MMA experience. He is also a certified Level 5 Police Jiu-Jitsu instructor.

Kevin Mans
Co-Owner & Coach
Kevin began training Brazilian Jiu-Jitsu in 2010 at age 35, after a recommendation from one of his younger soldiers. He earned his black belt in 2018 after eight years of training and is now a second-degree black belt.
He loves the physical and mental challenge of Jiu-Jitsu, along with the camaraderie it shares with military and emergency-service life. Kevin teaches all levels, from young children to advanced classes. His style is relaxed and approachable, but he knows when to roll hard.
Competition highlights
- 2024 JJIF Black Belt World Champion
- Two bronze medals and one silver medal at the World Masters Championships
