A good friend and co-worker of mine, and occasional training partner Jeff Starks, trains at the Fisticuffs MMA gym in Vancouver, Washington.

He has been training with Mike Fowler and Purebred's Enson Inoue, and at the recent Mike Fowler training camp Jeff was awarded his brown belt in BJJ!
Jeff has a very tight Jiu-jitsu game and is a force on the ground, this is a long awaited and well deserved promotion!
