This gym is simply excellent. Justen, the instructor, is extremely competent and his explanations are very precise and detail-oriented. The breath and depth of his understanding of every technique is incredible. On top of that, the lessons have a clear logical coherence and build on top of one another from one lesson to the next. The prices are definitely more than fair when comparing to other local academies. The culture at the gym is also very friendly and welcoming. Clearly, the instructors place great emphasis on using positive reinforcement and also on making martial arts accessible to beginners

Super grateful for Modern. Justen really is an amazing teacher; super analytical and extremely technical. BJJ is young enough that it has been changing and evolving rapidly, so it's super valuable to have a coach who continually tries to challenge and improve his own understanding of the art (which is already unbelievably deep). Instead of getting wrapped up in dogma and tradition, Justen genuinely evaluates the function of everything he does, then breaks that down to ensure everyone understands *why* we are doing something and the underlying principles/mechanics behind it.
Gym culture is super

I've joined Moder Martial Arts & Fitness's BJJ class for three months with previous experience. Justen is a solid coach for anyone interested in starting or advancing their BJJ skill. I appreciate how he teaches in a logical and detailed process. I am able to refine where I know and explore the new areas like the attach of legs. Also, his institute is the only one I found with requirement of a fully vaccination. I cannot appreciate his effort and commitment in preserving the sport as well as his students' health.

I have been training regularly at Modern Martial Arts for a couple of months now. Normally, I attend all or nearly all classes in a week. I have trained at a couple of gyms previously, and can confidently say this is one of the best gyms you can ask for. Justen's style of training is very precise; he has thought carefully about every position and teaches them very systematically. My BJJ has improved quickly because instead of learning a handful of seemingly random positions each class, we've methodically gone through a variety of positions and learned a sequence of appropriate responses from each

Modern Martial Arts and Fitness is a great place to train for all levels of BJJ and wrestling. Coach Justen's extensive knowledge and ability to breakdown technique makes learning much easier. The atmosphere of the gym is very open and welcoming. Prices are also comparable or better than other gyms. If you are looking to start training or for a new gym, I would highly recommend Modern!

I attended Modern MMA for about two months before moving out of town. Justen, Savannah, and Cherie run an operation that I cannot speak more highly of. As someone without martial arts experience, walking into a new gym learning a new sport can be somewhat nerve wracking, but from the second I walked in and was greeted by Cherie at the front desk, to the first session with Justen and Savannah up until my last, everyone I interacted with engaged with courtesy, respect and a smile. Yes the classes are tough (you will not get a better workout in any other group fitness format), but the feeling of accomplishment
