  •   I moved to Hamilton and started training under Jeff and his Cadre of Black Belts just over a year ago. Previously I trained under Rodrigo Munderuca in Winnipeg and Mike Yackulic in Edmonton, both amazing instructors. The dedication and skill level of EVERY Belt at Joslin's is on a level I have not seen before. This is no disrespect to my previous instructors as they have great clubs and great people. This is to say Joslin's really is something special and anyone who has any inclination of trying a martial art near Hamilton should come to Joslin's first. You won't regret it!

  •   Awesome gym with an amazing coach. The members are welcoming and everyone is there to help each other improve performance and fitness. As a female training jiu jitsu, I encourage other women who have been thinking about martial arts to come and try a class at Joslins.

  •   I'm only about 4 months in, but Joslin's has been such a great experience. I've felt welcome from the first day and everyone there is always excited to help out each other learn. On top of that, what a great workout... one of my goals was to get in better shape - and I'm already down 25lbs and my cardio is miles better than when I started. Thanks to Jeff and the entire Joslin team!
