About Ronaldo Jr

With 17 years dedicated to mastering the gentle art, Ronaldo Júnior brings the mindset, precision, and intensity of elite competition into every lesson he teaches.

Ronaldo’s Jiu-Jitsu journey is not just a story of dedication, it is a trajectory of victories at the highest level and a long-standing commitment to teaching.

A Career of World Titles and Elite Super Fights.

Committed to excellence from day one, Ronaldo has reached the top of the podium and faced the biggest names in the sport. His competitive experience is vast and proven:

  • IBJJF No-Gi World Champion – Black Belt (2023)
    A major accomplishment in his career, demonstrating the effectiveness of his techniques at the highest level of the sport.

  • IBJJF World Champion – Brown Belt (2019)
    Titles conquered in both Gi and No-Gi, solidifying his versatility.

  • IBJJF World Champion – Purple Belt (2018)
    The first world title, a milestone that paved the way for future success.

Beyond the World Championships, Ronaldo’s No-Gi techniques have been tested and validated in prestigious Super Fights, where he used his exclusive techniques to defeat and submit multiple black belt World Champions.

Throughout the years, he has had the opportunity to train under and be refined by some of the best professors in the world, consistently competing at the highest level. This elite experience has provided him with a refined technical arsenal, which forms the foundation of the courses he now offers.

Over a Decade of Jiu-Jitsu Instruction and Mentorship

Ronaldo’s passion for teaching began early. At just 16 years old, as a juvenile blue belt, he was already leading classes. Today, at 29, his experience as an instructor is combined with his background as a high-performance athlete, totaling more than a decade dedicated to developing students around the world.

His promise is clear: students will learn the same technical details and strategies that have allowed him to submit World Champions and conquer the most prestigious titles in Jiu-Jitsu.
