Ron Mukai Ron Mukai received his black belt in Brazilian jiu jitsu in 2017 and currently owns Ethos jiu jitsu in Fullerton, CA, where he continues to train daily, as well as teach the kids and adult classes.  Ron also competes and has won silver medals in the IBJJF Pans and the SJJIF Worlds as a brown belt as well as other regional tournaments.

     He is dedicated to his team and his students and wants to see each of them progress in art of jiu jitsu but, more importantly, to use jiu jitsu as a tool to build strong character and the skills necessary to deal with life’s physical and mental challenges.

     Ron’s path to jiu jitsu happened later in life (He started training when he was 39 years old), and the process of jiu jitsu completely changed every aspect of his life, his health, and how he faced personal hardship. This perspective allows him to teach smaller, weaker, slower individuals to overcome their physical shortcomings and use the techniques of jiu jitsu to control much bigger, stronger and faster opponents.

     Ron sees many parallels between his Christian faith and the principles of jiu jitsu including, faith, humility, perseverance, courage, loyalty and self control. He has been married to his beautiful wife, Wendy, for the last 23 years and they have 4 awesome kids: Diego (19 purple belt), Xanti (16 blue belt), Mila (11 grey belt) and Eze (7 grey belt).
