The leadership board reconvened to review an issue that had previously been brought before the organization involving a former member of the leadership board. When the allegations were first raised, the board removed the individual from any leadership role, allowing only limited affiliation while an ongoing civil proceeding awaited resolution, which remains unresolved.

This is an administrative governance decision made to uphold organizational standards and responsibilities. It is not a finding of fact and not a response to public commentary. Checkmat remains committed to maintaining a safe, professional, and respectful training environment across all affiliated academies. No further public comment will be made while the matter is pending.” Leandro Vieira Statement “To our community, We want to address this matter openly and directly. A recent allegation involving Coach Leandro was posted on social media by a former student and assistant coach who has not been part of our community for several years. While this allegation does not accurately represent the facts, we take any concerns raised about our academy very seriously. We want to clarify that this is not a criminal accusation. The matter is civil in nature and, due to its legal status, is now in the hands of the justice system. Coach Leandro has over 20 years of experience as a Brazilian Jiu-Jitsu black belt, teaching students of all ages around the world. Throughout those years, he has never had any allegation of misconduct. Those who train here know the values we live by every day: respect, discipline, and care for one another. Our commitment remains unchanged: to provide a safe, positive, and respectful environment for every student and family. We thank everyone for their understanding, trust, and continued support during this time.” Final note This article is informational in nature only.It does not constitute an investigation, accusation, or legal conclusion.
