Guru Karl Westin Bolz (Mas West) is from Charlotte, NC, and a licensed general contractor by trade. He began formal martial arts training in 1991 during college at UGA. He earned his black belt in American Kenpo under Steve Gresham and Dr. James Tindall. After studying Kenpo, Muay Thai, Kung Fu, FMA, and Jiu Jitsu, he was exposed to a rare art called Pencak Silat Serak. In 1999, he met Maha Guru Victor de Thouars, commonly known as Pak Vic. Pak Vic was a Dutch-Indo engineer by trade, who taught and preserved this elite close combat art that was passed down through his family. Pak Vic passed away in 2017, Guru West was fortunate to spend several days with him in his final week. Upon experiencing this Indonesian martial system that was directly effective but used subtle movements, Guru West dropped his other martial studies to focus on learning this rare treasure. He found the organization and breadth of the system daunting, but fascinating.
