Ralston Gracie
Brazilian Jiu-Jitsu Instructor
Ralston Gracie, the grandson of the founder of Gracie Jiu-Jitsu (also known as Brazilian Jiu-Jitsu) grew up in the North Bay and Contra Costa County. Learning closely under his father, Carley Gracie and brother Clark Gracie, his focus lies strictly on self defense and street-smarts tactics.
Competing in renowned Jiu-Jitsu competitions, he was awarded #1 place at a FIVE Grappling tournament in 2014, alongside honors in related events. Ralston has perfected the art of using his small frame to train others on how to use their strongest & most powerful body parts when attacked. Safety with grappling and drilling is a core focus of his, utilizing technique over strength that helps his students, of all body types, learn defense attacks to build stamina and confidence.
