Joslin's Mixed Martial Arts

Joslin's is an incredible gym to be a part of, not only do you get intense workouts, it teaches you valuable skills you can use for self defense and beyond. Jeff routinely shares the wisdom he has gained over a lifetime of competing at the highest levels, it's a privelage to be able to learn from him.

Started doing Joslins back in late 2020 with the bodyweight exercises. Throughout the lockdown doing online exercises up to now doing grappling and sparring, it has been nothing but amazing. Sensei Jeff, is a fantastic coach great mentor and motivates you to reach your potential and be the best. Thanks to his classes I feel like I'm in the best shape of my life and really helps dealing with my anxiety. Can't recommend this place enough. Thank you for all your work Sensei Jeff.

First time starting a martial art in mid-40s. Joined with teenage son and early twenties daughter. Jeff’s instruction is fantastic, you learn the fundamentals while getting great exercise and having fun. The classes offer something for people of all ages and levels of experience. I could not be happier to have joined.

Where to start? It's a great work out, great atmosphere!! The knowledge and fundamentals you learn is incredible , everyone there is friendly and helpful. I had no prior kickboxing experience and after day one I felt so comfortable and at home everyone is like a family there.. would highly recommend if you're simply going for a work out or if you're trying to be the next GSP it is suitable for everyone and all ages and it has dramatically helped me with my physical and mental state my self-esteem my self-confidence I can truly say starting up in December 2021 changed my life for the better !

Such a fantastic and welcoming community and Jeff is a phenomenal instructor! I came to Joslin's having trained BJJ for many years and have enjoyed the attention to detail that Jeff puts into all his lessons. There's always something there for people of all levels. Great place to train!

I have been training in Martial Arts on and off for the last 15 years or so. I've moved many times for various reasons and was lucky enough to train at several different gyms with a variety of people, professors and systems. Joslin's is unequivocally, the best gym I have ever been to in my life. It has absolutely everything you need to train at any level, heavy bags, sparring pads/mitts, mats, partners and even a full cage. But more importantly it has something no other gym can offer... Jeff Joslin. Jeff is the best instructor I have ever had. He invests in his students and he cares. The more you put in the more he gives. He laughs, struggles, sweats and bleeds with us on those mats day in and day out. I've met a lot of arrogant teachers with resumès nowhere near as impressive. If he wanted to he could easily be arrogant and boastful, and yet he is the most humble, considerate and respectful professor I've ever had the pleasure of training with. And in turn, he earns the respect he has from his students every single day from leading by example. Jiu-Jitsu has changed my life. I could write a 10-page essay on it's benefits. I began going mostly for the physical activity and self-defense, but I'm beginning to notice such a positive effect on my mental health that I now consider it a fun way to clear my mind, develop new skills and bond with like-minded people. The struggles you go through on those mats really help harden and prepare you for other aspects of life, and truthfully... you couldn't possibly choose a better place with a better teacher and group of people to grow with. Whatever age, weight or issues you may have. Don't think about it, just come in, say hi and start training.

Have been here sporadically throughout the years but have always had phenomenal experiences. The kickboxing classes are constructed very well, always a killer workout. Jeff is a fantastic instructor and takes the time to help you 1-1 if needed. So happy I rejoined! Kickboxing is an awesome outlet for stress :)

My experiences at Joslin’s have been nothing but amazing for years. I started off many years ago in the kids BJJ classes and then transitioned to the adults, and throughout all of those classes and instructors at Joslin’s, I felt so comfortable and happy and excited to train. Jeff himself is an incredible instructor who is extremely knowledge in all the martial arts offered, but aside from technical expertise it’s the fantastic environment he creates that kept me coming back. There are nothing but positive vibes in the classes, and it drives you to work harder while still enjoying every class. I highly recommend this gym for anyone looking to get fit, pick up a new hobby, or find a great community to help them get into the martial arts world for all ages!
