Robert S. Kaelin

Roberto Kaelin is the owner of Viper Brazilian Jiu-Jitsu in Keller, Texas, which he opened in 2007. He began martial arts as a child, by his own account not an especially athletic or confident kid, and describes that training as one of the most formative experiences of his life; it was long his dream to own a school where students could build fitness and confidence they could carry into everyday life. Testimonials on the academy's site identify him as a Carlos Machado BJJ black belt. Viper is an IBJJF-certified academy and, according to the site, the only one in Tarrant County offering instruction and rank in both Brazilian Jiu-Jitsu and judo, with beginner and advanced programs for kids and adults.
