Welcome to Zinkin Entertainment, world-class management for world-class athletes. Under the guidance of Crazy Bob Cook (an undefeated UFC veteran and head coach at the American Kickboxing Academy), we have guided the careers of MMA stars like Chuck Liddell, Paul Buentello, and Josh Koscheck. Our goal is to serve the MMA community by showcasing athletes who have both the ability and drive to go all the way, to compete at the highest level and to dominate on all fronts. As a fighter himself, Crazy Bob has the unique ability to speak to his teammates on their level, to provide a voice of experience and reason both inside and outside the ring. Throughout his career as a trainer and manager, Bob has displayed strong business savvy in dealing with both his peers and his competitors, a low-key confidence that has established him as one of the best in the business. Bob has set the standard for our management team, dedicating himself to providing the most comprehensive management possible; our priority is and always has been to secure both the reputation and financial future of the athletes that we represent.

In joining forces with Dewayne Zinkin (an NCAA division I All-American wrestler), Crazy Bob Cook has taken the final step in creating one of the most complete full-service management teams in the world of MMA. As a partner, Dewayne Zinkin has provided even greater insight into the legalities of securing and promoting fighters, his expertise and contribution have strengthened an already powerful force in the world of MMA. We consider all of our athletes champions, although not all have been given the opportunity to prove themselves worthy of that title. Our goal for the future is to continue to produce world-class athletes who are not only able to compete at the highest level, but are able to do so with style and grace; we strive to create fighters who are as exciting as they are technical, who have the skill, confidence, and personal appeal to represent the sport in the best possible light. We are proud to serve both the fighters that we represent and the fans who make it all possible.
