  •   Great place to challenge yourself mentally and physically love the people I have met over the years and always welcoming the new comers and get them to work hard and push them out of their comfort zone

  •   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.

  •   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.
