Groundwork Grappling


Brazilian Jiu Jitsu is an incredible self defense system based on principles of technique and leverage, designed to allow practitioners to defeat opponents of a much greater size and strength. This means you don't have to be big, fast or strong to be an effective practitioner. Brazilian Jiu Jitsu was established in 1925, and has been proven to be one of the most effective forms of self defense.

Groundwork Grappling is proud to offer traditional  Brazillian JiuJitsu classes. We are a Cleber Luciano affiliate Brazilian Jiu Jitsu school. Our mission is to build confidence and share Brazilian Jiu Jisu with all of Northern Wisconsin. We have programs designed for all age, skill and fitness levels.

Jared Raths- 2nd Degree Black Belt

Coach Jared Raths is a 2nd degree Brazilian Jiu Jitsu black belt under Master Cleber Luciano. Coach Raths has competed at different levels of Jiu Jitsu and is pleased to share his over 15 years of experience. Coach Raths has instructed and trained students in Traditional and Sport Jiu Jitsu, Mixed Martial Arts and Self Defense.

Coach Raths founded Groundwork Grappling 4 years ago in  Downtown Rhinelander to be able to share this art and passion with the Northwoods. He is grateful for our wonderful community and the ability to share what he loves. Come down and say hi and see what we are all about.

Cleber Luciano- 6th Degree Black Belt

Cleber Luciano started training in Judo at age 5 and started Brazilian Jiu-Jitsu at age 7. Even at a young age, Cleber’s dedication and perseverance stood out. He received his Black Belt in Jiu-Jitsu under Professor Royler Gracie at the age of 19. He holds a Black Belt in Judo as well.

Groundwork Grappling is proud to affiliate with Cleber, and host him for seminars on a regular basis. What Cleber brings to the mats makes all of our students better.

Great gym with a motivated instructor. I've enjoyed visiting and training with Jared for a few years now and it's always a pleasure. Definitely the gym for Brazilian Jiu Jitsu if you're in the area.
