Jeff “Flow Rida” Mueller moved up in the Brazilian Jiu Jitsu ranks to Blue Belt. Jeff comes from a traditional martial arts background and began training at Crazy 88 in May 2008. He has grown to become a valuable member of the team and demonstrated his dedication to his MMA training by continuing to train when his job sent him to Florida. Jeff would train the evenings when he could in Tampa, and after flying back to Baltimore on Friday evening, he would come into our Baltimore school for the Saturday class. Congratulations to Jeff!
