OUR TEAM

THE MILLER BROTHERS

We're the Miller Brothers, Seth and Ray. As university certified educators we founded Spectrum with the desire to use our teaching skills to introduce you to the world of Brazilian Jiu-Jitsu. We both hold brown belts in Brazilian Jiu-Jitsu. Our aim is to offer the most modern and comprehensive instruction in the area.

We hope to enrich the community we grew up in and want to avoid high tuition and the unnecessary nickel-and-diming that martial arts businesses are notorious for.

We have been training in the martial arts for over fifteen years. In our academy we seek to provide and maintain an ever-growing arsenal of the most efficient and proven techniques. The focus will remain on producing supreme martial artists, athletes, and people rather than simply a belt to show off.

Our mission is to train others to improve their mind and body by learning the techniques of Brazilian Jiu-Jitsu.
