Mason Fowler is a professional grappler and a representative of the Caio Terra Association (CTA) in jiu-jitsu's professional circuit, who holds the rank of black belt. A student of Caio Terra, who worked extensively with Gabriel Procópio, Fowler became a familiar face in the sport's international circuit after his dominant performance at the ADCC West Coast Trials back in 2019, a good form he continued to display in the years that followed, which earned the California native several wins over some of jiu-jitsu's most well-respected competitors.
