Crazy 88 Mixed Martial Arts Instructors & Coaches

With only one exception, every single Crazy 88 instructor started as a Crazy 88 student. Because they all started in the same place, they know exactly what pitfalls to help you avoid and what shortcuts to take (and which ones not to).

Each instructor at Crazy 88 has put in a minimum of 5 years into understanding and mastering their particular martial art. In addition, all our instructors participate in ongoing training as they are continuing students themselves. All of them of have competed in their field – whether its in Jiu-Jitsu, Mixed Martial Arts, or Kickboxing. They know what works and they’re eager to help you learn it.

Our ultimate objective is to to get you the results you determine for yourself. Our staff is very focused on helping you learn and get in shape in the most effective way possible for your goals and fitness level. To accomplish this, we have proprietary training curriculum for each martial art we teach, a thorough and ever-growing online video library, as well as specialty workshops and clinics. Furthermore, our instructors go through continuous learning on how to teach more effectively in their respective martial art.

Probably the thing you’ll enjoy the most is that the teaching style of our staff is friendly and supportive. You can expect great rapport with our instructors as well as rely on them to be accessible when needed. Many of our members comment on how our training environment really helped them overcome hurdles in their own personal martial arts training because of how effective and available are instructors are.

Quotes about our Baltimore Martial Arts Instructors

quote about Crazy 88 Martial Arts Instructors

Maryland Engineer testimonial

What I love about Crazy 88 is that you get to progress at your own pace. If you want to be a world champion pro Jiu Jitsu athlete, we produce them. If you’re the guy who shows up two times a week after a long day at work and you just want to sweat and enjoy some good-natured camaraderie, you can have that too. It’s a rare environment where you can do it all and not feel out of place.

– Jeff, Presales Engineer
