KOA Martial Arts (BJJ, Muay Thai, & MMA) in Stafford, Virginia, is led by Professor Kelly Grissom, a 3rd degree black belt under Leo Dalla and part of the Big Brothers / Leo Dalla Jiu Jitsu Association. Grissom’s instruction follows a lineage that emphasizes traditional martial arts values alongside the practical self-defense techniques of Gracie Jiu Jitsu and Muay Thai kickboxing. The academy’s mission focuses on developing responsible, self-aware practitioners through disciplined training rooted in both tradition and effective combat skills. Training at KOA covers Brazilian Jiu Jitsu in both gi and no-gi formats, wrestling, classic Muay Thai striking, and specialized programs for children. The curriculum supports a variety of goals—from lifestyle changes and fitness to fight preparation—reflecting an understanding of martial arts as a path that extends beyond competition. The team includes multiple black belts under Grissom, along with a Muay Thai Kru, ensuring depth across disciplines. Classes run six days a week in a wheelchair-accessible facility at 50 Dunn Drive, and the academy offers a no-cost trial for newcomers. Beyond scheduled classes, KOA provides a setting that respects traditional martial values while encouraging continuous improvement, encapsulated by Grissom’s motto: “Never Settle. Improve your position.”
