  •   I would recommend that anyone who is even remotely interested in MMA and has a good attitude sign up at Joslin's now and just try it out. The encouragement I receive each day, along with the self-confidence of knowing I can defend myself has really made my life better. My day is just not the same unless I've hit the mats and learned something new. Everyone there is awesome and always willing to help you learn and grow. I look forward to the next class more and more every time I go and am in the best shape of my life thanks to training at Joslin's!

    thumb Ryan Anderson
  •   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!

    thumb Jay Wily
  •   Always fun to train in a club that makes you feel welcome. Great group of people to train with. Also the instructors are knowledgable and always trying to introduce new things in your jujitsu life.
