Hello

Welcome to Martial Arts Grand Traverse — MAGT for short, formerly known as ATA Martial Arts.


New name, same ownership & commitment to helping you grow stronger, inside and out!

At MAGT, we believe martial arts is more than kicks and punches —it’s a powerful path to confidence, focus, and lifelong personal growth. Our high-energy classes and inclusive community help kids, teens, and adults build strength, resilience, and real-world skills that go far beyond wearing the Dobok on the mat.

We’re not just building martial artists —we’re building unstoppable humans!

We are a female — owned and operated Dojang located in northern michigan
