Following his relocation to Las Vegas, Marc Laimon established himself as one of the most respected grappling coaches in the United States. His reputation rested on a technical and pedagogical approach that blended No-Gi expertise with a rigorous kimono-based foundation — reflecting his conviction that the gi serves as the bedrock upon which all BJJ skills should be developed.
In 2004, Laimon co-founded Cobra Kai BJJ, becoming the academy's leader and most prominent figurehead. Under his direction, Cobra Kai grew into a recognized force in competitive grappling, producing accomplished black belts such as Sim Go and Chris Holdsworth. His influence extended into mixed martial arts as well, with coaching contributions benefiting high-profile fighters including Bas Rutten, Oleg Taktarov, Mark Kerr, and Johny Hendricks, among others.
The broader grappling community formally recognized his contributions in 2005, when On The Mat voted him Instructor of the Year. His subsequent induction into the Grapplers Quest Grappling Hall of Fame cemented his standing as a transformative figure in American BJJ coaching.
