Trey Mundine

Trey Mundine is a Brazilian Jiu-Jitsu black belt and BJJ/MMA coach at Corsair BJJ in Elgin, TX. He started jiu-jitsu in 2006 under Phil Cardella, earned his purple belt in 2009, and received his black belt in 2020 from Derrick Garza. Soon after he began training, he started competing in BJJ and then mixed martial arts, where he holds a 2–1 record.

Trey has been teaching since purple belt. He first coached at the original Relson Gracie Austin academy, later served as co-head grappling coach at Kamal Shalorus’s Arete Training Center, and has been an assistant instructor at Dark Clan Fight Lab, 10th Planet Austin, and Relson Gracie South Austin. He has also coached and cornered professional and amateur MMA fighters.

His training room has included some of the best no-gi and gi grappling in the world: Craig Jones, Lachlan Giles, Daniel and Diego Moraes, Robert Drysdale, Relson Gracie, Royler Gracie, and Paulo Brandao. That mix shows up in class—position before submission, wrestling into the fight, and techniques that work with or without the gi.

Trey’s focus today is no-gi submission grappling and MMA, with gi work when it serves the student. Competition highlights include the 2015 AGF San Antonio Pro title (under 160 lbs) and the 2009 NAGA Texas State expert title (145 lbs). At Corsair he teaches adult Brazilian Jiu-Jitsu for people who want self-defense, fitness, or a path into competition.
