  •   Professor Double J (thats J-E-double F, J-O-S-L-I-N) is an absolute inspiration for me. He balances the family, multiple job duties (including the gym) and does it all with genuine love and desire. He has a very contagious energy and personality that makes all feel welcome. His output on the mat is second to none, and at his age it just goes to show that if you apply yourself, anything is possible. Nobody acquires and shares knowledge at the level Jeff does, and the best part of it all is that he doesn't try to go out on a limb to prove himself: all the proof you need is to simply be a part of it. Everyone at the gym is friendly and helpful. Great leadership builds great character. I would recommend this gym to anyone.

  •   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!

  •   No question. 5 stars! This is a world class gym with great people! Jeff takes a lead role in running his business and doesn't pawn off responsibility. I learned a lot and had one of the hardest work outs I've had in a long time. Very fair pricing and wide open scheduling. Recommended and highly!

  •   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!
