Our Brazilian Jiu Jitsu Instructors

One of the most unique characteristics distinguishing Kimura BJJ from other martial arts schools is the way in which Kimura instructors are trained and developed.

The philosophy of Kimura BJJ for instructor training and development is very simple: develop instructor talent from within or as we like to say “Our instructors are created at Kimura BJJ day by day, one by one, from day one.”

With few exceptions, Kimura instructors began their BJJ journey toward mastery under Master Jean Kleber. This philosophy helps to maintain Kimura’s authenticity and purity without any dilution of the original teaching methodology, technique, or philosophy of Kimura’s founders. This translates into Kimura students receiving a consistent teaching message, curriculum, and learning structure from all Kimura instructors at all of our branches.

Before ever taking charge of a class, every Kimura BJJ instructor is required to complete a comprehensive apprenticeship under Master Jean Kleber in order to fully understand all of the qualities necessary to provide Kimura BJJ students with the best possible training experience.

Master Jean Kleber de Freitas

Master Jean is the founder and owner of Kimura BJJ U.S.A. He is a 3rd degree Black Belt certified by the IBJJF, USJJF, COBJJ, and CBJJ. Master Jean has spent his lifetime advancing the art of Brazilian Jiu-Jitsu. From launching Kimura BJJ in Europe and teaching seminars around the world, to his founding of Kimura BJJ in the U.S., Master Jean has already left his significant impact on the art of BJJ, and he continues to bring his world-class experience and knowledge to all Kimura BJJ students.

Master Jean has been training in BJJ since 1992 and teaching BJJ since 1995. He is also proficient in submission wrestling, judo, Muay-Thai, Vale Tudo, Mixed Martial Arts (MMA) and self-defense. A fierce competitor from the very beginning of his own BJJ training, Master Jean is a winner of countless victories and championships in world- class tournaments around the world (see Master Jean’s tournament record). There are few practitioners of the art of BJJ with the level of experience and knowledge of Master Jean, and fewer still who maintain a daily presence in their own schools, and who actively teach classes and train their students directly.
