Kimura BJJ Academy

Master Jean Kleber

Born in Natal, Brazil, Jean Kleber discovered the art of Brazilian Jiu-jitsu and started training at the age of 14. After a year of training, Jean was introduced to Master Jair Lourenco, founder of the first Kimura Jiu-jitsu academy in Brazil. Lourenco immediately saw potential in Jean and asked him to join the Kimura competition team. Shortly after joining Team Kimura, Jean competed in the Rio Grande do Norte State Championship; it was his first tournament of many to come.

In 1995, in addition to competing in tournaments throughout Brazil, Jean’s master Jair Lourenco and his business partner invited Jean to become an instructor for a class at the Kimura academy. Already known for his exceptional abilities as a fighter and competitor, Jean began to gain new recognition within the BJJ community and also by the local media for his extraordinary talent as an instructor.

As a result of Kimura’s growing popularity and recognition for excellence, its student population increased, which led to the opening of an additional Kimura school. At the same time, Master Andre Pederneiras invited Team Kimura to join forces with the Nova Uniao Jiu-jitsu team of Brazil. The joining of Kimura with Nova Uniao gave Team Kimura members the opportunity to further hone and refine their skills and to take their technical ability to a new level of proficiency.

After the Nova Uniao/Kimura union was formed, Jean Kleber’s popularity as a competitor and teacher continued to grow throughout the BJJ community and beyond. He competed in tournaments throughout Brazil, with many of his competitions drawing thousands of spectators and national print and television coverage. During this time, Jean also took the opportunity to teach seminars in Brazil and Europe, spreading the art of Jiu-jitsu everywhere he went.

In 2001 Jean moved to Portugal and opened the first Kimura Jiu-jitsu School outside of Brazil. After firmly establishing the school, he asked Dinarte Silva, a black belt, to continue with development of Kimura BJJ in Portugal.

In 2003, Jean Kleber moved to the United States where he met Steve Giroux, owner of Giroux Brothers Martial Arts School. Steve offered Jean the use of his space to start the first Kimura BJJ academy in the USA. Once again, word of Jean’s ability as a teacher and technical knowledge of Jiu-jitsu spread rapidly throughout New England. Kimura BJJ USA continues to grow and flourish to this day along with Master Jean’s reputation as one of the world’s elite Brazilian Jiu-Jitsu instructors and practitioners.
