Meet the Professor

“The Professor” Clint Crabtree started wrestling at 5 years old. During his wrestling career, he won 4 State Championships and 1 National Championship. Clint continued wrestling his entire life and during his time in the military, serving his country, he was victorious in winning the All- Army European Wrestling Championship.

Clint has been involved in BJJ for 15 years and is a 1st degree Black Belt under world famous Master Carlson Gracie Jr. He is currently the only Carlson Gracie black belt in Michigan and the only legitimate, certified black belt in West Michigan.

Professor Crabtree started GRBJJ 12 years ago with 1 one student in Wayland, MI. and built it into the powerhouse here today. Our Academy has one of the largest facilities in the Midwest and is equipped with the world famous Zebra mats, the same mats used at the world and pan am championships.

Clint took 2nd place in the BJJ world No-Gi championships and 1st place at the Pan-Am Championship, and is a 6 time Arnold Classic Champion, a 7-time NAGA expert champion, Budweiser World Cup champion and a 3 time Gracie National champion!

Professor Crabtree is proud to have trained with World champions including Master Carlson Gracie Sr. and Master Carlson Gracie Jr., Royler Gracie, Royce Gracie, Marcelo Garcia, Hermes Franca, Fredson Paixao, and his good friend Robson Moura who comes to GRBJJ at least once a year to train.

Our accomplished BJJ and MMA teams have competed all over the Midwest, and the nation at the highest levels winning numerous team championships including the 2009 ADCC Team Champion.

We are proud to continue the legacy and teaching of Master Carlson Gracie Sr., “Tradition, Dedication, Honor”. Here at GRBJJ we don’t give belts away, you EARN them.

If someone is teaching BJJ in west Michigan, chances are they trained here at GRBJJ, this is why people refer to GRBJJ as, “The Source”.
