  • Alex Guerrero

    Alex Guerrero is a first degree Gracie black belt. He got started in Jiu Jitsu twelve years ago when he signed up his sons at the Gracie academy in Dublin. However it wasn’t until a year later until Alex decided to step on the mats and give Jiu Jitsu a try. After being dominated by someone weighing a hundred pounds less than he, Alex knew he had to learn the art of Jiu Jitsu. Over the next eleven years Alex would go from a 260 pound white belt to a 200 pound black belt, eventually earning the head instructor position at the very same academy he stepped foot in over a decade ago. Jiu Jitsu made such a positive impact on Alex's life, both for his health and family, that it became his life's goal to share his love of Jiu Jitsu with as many people as possible. Anyone who has experienced Alex's teaching style can attest he is one of the best in the Bay Area.

    Classes: Kids, Fundamentals, Advanced, and Competition class.
