("Mo" is the nation of Sudan's first Brazilian Jiu Jitsu black belt. He was promoted to black belt in Senegal at the 2023 "Championnats du Senegal Jiu Jitsu Bresilien" (aka the Dakar Open) hosted by the Bokk Jiu Jitsu team in Dakar. Shortly after Mo’s return home in 2023, the (current) Sudanese civil war started and he essentially lost everything as his family was separated by the conflict, including his hard-built school. Mo now lives and teaches Jiu Jitsu and Muay Thai here in the US in the N. Virginia area at Beta Academy under the leadership of my friend and JJ mentor, Nakaphan).
