Led by a Legend: Master Leo Vieira

Checkmat’s success is guided by Master Leo Vieira, a 5th-degree BJJ black belt and Judo black belt. Known as "Leozinho" (Little Lion), he is a two-time World Champion and two-time ADCC winner, respected for both his technical mastery and coaching innovation.

Master Leo’s philosophy goes beyond just winning medals—he sees BJJ as an art, a science, and a tool for personal transformation. Whether he’s coaching a world champion, a police officer, a nurse, or a complete beginner, he brings the same passion, kindness, and dedication to every student.

At Checkmat, we believe in building a stronger, healthier, and more positive community—together.
