Before discovering BJJ in 2000, he trained extensively in Japanese Jiu Jitsu and Judo under sensei Karel Gietelink, and was awarded his black belt in Japanese Jiu Jitsu through the Judo Bond Nederland. Daniël’s first BJJ instructor, Mike Yanez of Team Popovitch, introduced him to Folkstyle Wrestling. He has been blending Wrestling with his BJJ ever since, along with basic Judo, and has consistently trained in the No-Gi, MMA and Self Defense variations of BJJ as well. Daniël is an active competitor in the middle weight division, but his real passion is teaching BJJ and helping people to grow in this fantastic art.
