Guilherme Cotliarenko

profesor gui

Professor Guilherme Cotliarenko (Prof. “Gi”) started his Jiu Jitsu journey while living in his native Porto Alegre, Rio Grande de Sol, Brasil. Prior to discovering the gentle art, he studied Capoeira for over four years and surfed at every opportunity. Once introduced to Brazilian Jiu Jitsu, Guilherme quickly decided to focus his energy. He achieved his blue belt and won one Muay Thai and two MMA fights he entered before traveling to California to compete in the IBJJF World Championships in 2009. After the competition, Gracie Barra Black Belt Professor Ulpiano Malachias welcomed him to stay in the United States. Here Professor Gui was awarded his purple belt, started training for more MMA fights, and began his career as a Gracie Barra instructor.

Professor Guilherme has since achieved his First Degree Black Belt, been awarded by Master Carlos Gracie, Jr in 2016, and taught hundreds of children and adults at Gracie Barra schools in Southern California and Texas. He loves spreading his vast knowledge of this beloved martial art and helping his students achieve their personal goals on and off the mats. He also still surfs at local breaks every chance that he gets!

Professor Gui has Gracie Barra to thank for more than just his career in Jiu Jitsu! He met his now wife, Anya, at Gracie Barra Headquarters in Irvine while both prepared to compete at the IBJJF Pan Championships. She is a veterinarian and works for the United States Department of Agriculture in the Los Angeles area. They married in 2014 and still love training together! The Cotliarenkos recently welcomed their first child, Enzo, and are excited for him to enjoy the Jiu Jitsu lifestyle in the future.
