Our Instructors
Cristyan Brazilian Jiu-Jitsu is led by Professor Cristyan Devanir Martins, a 4th-degree black belt in Brazilian Jiu-Jitsu with decades of experience in martial arts training and instruction.
In 2012, Professor Cristyan founded Evolution Jiu-Jitsu Martial Arts School, where he began building a strong martial arts community focused on both technical excellence and personal development.
That same year, the academy began a specialized training program for children, creating structured classes designed to help young students build confidence, coordination, and discipline through Brazilian Jiu-Jitsu.
