  •   Jeff has a very organized curriculum in place. A really great environment to learn in!

  •   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!

  •   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 signed up as a member approximately 7 years ago now and have never looked back. As a member, it is hard not to feel part of a strong loyal family unit. Strength was found in mind, body and spirit on the mats, transcending into daily life. The Joslins team is supportive, the quality of instruction is superior and words can not fully portray how grateful i am to be part of such an amazing community.

  •   Been training here for 3 and a half years now, I don't plan on stopping any time soon. It is different every day, every instructor takes the time to explain everything and help you with the details, and everyone always has a great time. Super fun and great people to share it with

  •   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!

  •   You can't go wrong here. The Joslin family and team have big hearts and love helping people. They are also renowned and among the best in the world of mixed martial arts. People of all ages, shapes and sizes, and walks of life will gain something and feel welcome.
