Isaac Doederlein is an American Brazilian Jiu-Jitsu black belt under the legendary Rubens Charles, also known as “Cobrinha”.
Isaac began his martial arts journey ~18 years ago, when his mother signed him on her church’s group judo program at the age of 11. Doederlein stuck to the course up until his 14th birthday when he moved to Arizona opting to join a jiu-jitsu academy. At the age of 18, one month after finishing High School, Isaac Doederlein decided to invest everything into his passion, and move to Los Angeles. His goal was to train under Cobrinha full time, in hopes to fulfill a life’s dream of becoming a World Champion.
