Matt "Sumo" Shriner
Matt is a BJJ black belt and 2x IBJJF World Masters champion, promoted under coral belt Marco Nascimento. Before jiu jitsu he earned a black belt in full-contact karate and competed in Japan, and trained Muay Thai at Fairtex in Thailand. Longevity BJJ came out of those years on the mat: a way to keep training hard without the body paying for it as you get older.
