Mauricio Alonso's BJJ school is the best place to learn self-defense skills. The instructors emphasize technique and strategy, making it an excellent choice for anyone looking to improve their martial arts skills.

Lucas Choi Yum

Awesome place to learn jiu jitsu with a wide range of people to train with. The head coach Mauricio is a world class fighter and 4th degree black belt under the legendary Master Ryan Gracie. I've been training with Mauricio for more than 11 years and this is one of the best places to learn Jiu Jitsu in the country. Whether you're a new white belt or a seasoned competitor, this is the place to be.

Max Ottersbach

I have been training at Mauricio’s gym for almost a decade now.  Mauricio is a master in the art of Brazilian Jiujitsu, an expert in self defense and mixed martial arts and also a friend and a positive energy at the gym. If you’re looking for the real deal in the East bay, Mauricio Alonso BJJ is the gym.
