“The Professor” Clint Crabtree started wrestling at 5 years old. During his wrestling career, he won 4 State Free Style Championships and 1 National Freestyle 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 23 years and is a 3rd degree Black Belt awarded by Master Carlson Gracie Jr. He is the first Carlson Gracie black belt in Michigan.

Professor Crabtree started GRBJJ about 22 years ago with 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 Champion.  GRBJJ is proud to be apart of the World famous GFT team (Grappling Fight Team),  GRBJJ is proud to have been selected by such a powerhouse team to be the first BJJ academy in Michigan to represent GFT.  Look for world class seminars by multiple world champions to be happening at GRBJJ on a regular basis.

Here at GRBJJ we don’t give belts away, you EARN them.  You will know each step of the way, that you have made yourself 1% better each day.  That you earn everything you receive from GRBJJ.  Come in ready to train, regardless of your team affiliation  (or lack of).  We truly live by these words, “No Politics, No BS,,, Shut up and Train”.  No tribalism mentality here.  What matters is not who you claim to represent, but YOU!  How can we work together to make you better each and every time you come in to train?

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”.
