Jiu Jitsu Black Belt

"I started Jiu Jitsu at a late age after spending 25 years doing Shotokan, Kenpo Karate, Chinese Boxing, Kick Boxing, Sprinting and Weight Training. I fell in love with Jiu Jitsu during the first class. I was manhandled by someone half my weight and all my fighting skills were useless on the ground.


It was a hugely humbling experience. I signed up straight away and like all things in my life I threw myself into it until it became my entire life.


I always loved competing and Jiu Jitsu gives you that platform every few weeks. The next best decision I made was to open my own club to train my daughter and help other people find Jiu Jitsu and help change their lives too."

Nathan O'Callaghan

World Champion / IBJJF European Champion / Irish Open Champion

Jiu Jitsu Brown Belt

"I have been in this sport since a young age. It’s all I know and I really love it.  It’s my life and Checkmat Dublin is my family. At the club, the team helped me push myself to become World Champion and IBJJF European Champion. You can’t get anywhere in this sport without sportsmanship and most of all friendship. I can’t wait for what 2024 has to offer"

I came to Checkmat Dublin in summer 2023. 


Checkmat Dublin has since become my new home and my interest in competing has been reignited.


I recently started teaching NO GI Fundamentals.
