Duality Bjj LLC

Duality Bjj LLC in Green River, Wyoming, is led by Casey Barnum, a brown belt under Professor Danny Richards, who carries a lineage tracing back through Romero Cavalcanti and Rolls Gracie to the founders of Brazilian Jiu-Jitsu. Casey’s background includes wrestling from childhood through college, a purple belt in CSW, and years of experience in MMA, which shapes the academy’s practical, fight-oriented approach. Co-owner Adella Barnum, also a brown belt under Kurt Osiander and Professor Danny, complements the instruction with a focus on technique and progression, reflecting their shared commitment to steady, skill-based development. The academy offers training in Brazilian Jiu-Jitsu alongside self-defense, Judo, wrestling, CSW (Combat Submission Wrestling), MMA, and striking arts. Classes emphasize learning solid habits and patterns that apply both on the mat and in real-life scenarios. Students can expect a range of programs designed to engage different interests and needs, from fundamentals to more advanced grappling and stand-up disciplines. Women’s self-defense and law enforcement tactics are part of the curriculum, reflecting the instructors’ broad coaching experience. Training sessions include gi and no-gi Brazilian Jiu-Jitsu, wrestling drills, and open mat times for adults to refine techniques or prepare for competition. The academy operates out of a wheelchair-accessible facility, located at 142 E Flaming Gorge Way, making it accessible to a wide range of practitioners. Drop-ins are accepted, allowing newcomers to try classes before committing. Duality Bjj’s approach is practical and paced to meet students where they are, focusing on long-term growth and resilience both physically and mentally.
