COR Jiu Jitsu

COR Jiu Jitsu is led by Nick Metzinger, a black belt who began training in 2008 under Roman Kilgore, himself a black belt under Carlos Machado. Nick’s approach to instruction emphasizes consistent skill development through regular practice and attention to fundamentals, a philosophy shaped by his own progression and competition experience. The academy also benefits from the involvement of his family members, including his sons Nicholas and Adam, who hold black and brown belts respectively, and assistant instructors like Greg Kish, whose diverse martial arts background spans karate, judo, boxing, kickboxing, and aikido. Classes at COR focus primarily on traditional gi Brazilian Jiu-Jitsu for adults, with sessions held on Monday and Wednesday evenings. Instruction balances technique drilling with live rolling, allowing practitioners to apply concepts in dynamic settings. The school also hosts open mat sessions on Sundays, providing additional time for students to refine skills or explore specific areas of interest. The program structure supports steady progression from fundamentals to more advanced techniques, reflecting the academy’s emphasis on long-term growth. COR Jiu Jitsu operates within the Heights Recreation Center in Richardson, TX, a wheelchair-accessible facility that welcomes drop-in students. The academy also runs a dedicated kids program under the guidance of Michael Nguyen, a black belt and lifelong martial artist who focuses on helping younger practitioners reach their potential. This multi-generational teaching team contributes to a stable environment where experience and fresh perspectives come together to maintain a steady path of improvement.
