Changing Lives for Over 25 Years

Founded in 1999, America’s Best Defense is dedicated to transforming lives through Martial Arts. Regardless of age, gender, fitness, or experience. Our schools provide a safe, comfortable and welcoming atmosphere where students truly thrive. Our certified instructors are world-class and are here to help you learn new skills, achieve your goals, and build lasting connections.

Kids Martial Arts

Designed by an 8th degree Black Belt and a Child Phycologist, our Kids Martial Arts program has helped thousands of children build confidence, focus, discipline, respect, all while learning practical and safe self defense skills.

Krav Maga
Self Defense

Krav Maga is the world’s leading self-defense system for adults, and our certified instructors teach in a way that's welcoming and empowering. Each class sharpens your ability to protect yourself, burns calories, and builds genuine confidence, so you leave every class sweaty, sore, and smiling.

More Then a Gym

I can’t say enough great things about ABD. This place has become more than a gym, it’s a community of people that I genuinely look forward to seeing every week.

Increased Confidence

My child's confidence has gone through the roof since we enrolled at ABD. He went from shy and nervous, to introducing himself to new kids and taking charge!

Best Instructors

The instructors at ABD are unlike any I've experienced before. They're so knowledgeable, kind, and great teachers. They clearly believe what they teach.
