2. Isaac Doederlein’s Biography

Isaac Doederlein is a Brazilian-American black belt under the famous Rubens Charles or “Cobrinha.” From his time as a blue belt to now, Doederlein won several medals and a huge fan base worldwide. In 2019, he also became the third American and the second in the male division to win the Brazilian Nationals.

2.1. Early Childhood

Doederlein was born in Atlanta, Georgia in the United States of America on November 12, 1992.

2.2.  Grappling Training

Doederlein’s mother enrolled him in her church’s judo program when he was 11 years old. At the age of 14, when his family moved to Arizona, Doederlain continued his grappling training at a jiu-jitsu academy.

2.3. Training Under Wellington Dias

In Arizona, Doederlein learned under Wellington Dias, a pro in grappling in that region. At the Gracie Humaita academy, Doederlain began competing in various competitions. 

2.4.  Winning a World Title

Doederlein won his first IBJJF World Championship two years after becoming a blue belt.

2.5. Training at Rubens Charles’s Academy

At the age of 18, Doederelin decided to visit Rubens Charles’s academy. After moving to Los Angeles and joining Rubens Charles’s academy, he became a full-time athlete and pro grappler.

2.6.  Promotion to Black Belt

Doedelein joined Cobrinha’s academy as a purple belt, earning his brown and black belts from Rubens Charles in 2022.


When asked about the traits necessary to win a difficult jiu-jitsu tournament when he set to compete at Sao Paulo, Doederlein said,

“I think what especially makes it different is the atmosphere of the venue, and the crowd making it more exciting... I do think this is a tough question to answer because every division is different and it just depends on who signs up! But overall I believe there will be no easy rounds as everyone in Brazil is really tough!”

Doederlein’s perseverance is one of his defining traits. According to him,

“I’m always challenging myself with different situations and techniques, almost like a puzzle. This constant work focused on evolution feeds my passion for Jiu-Jitsu and keeps me from burning out. Regardless of whatever outcomes I’ve had in the past, my focus is always on winning.”
