In the mid 90’s Jason found the love for Jiu-jitsu through a training partner who had earned his Blue Belt from Royce Gracie. After taking over Wilcoxen’s Academy in 2007 Jason fell in love with the 10th Planet System from life-long friend and training partner Derek Stewart of 10th Planet Omaha eventually changing the name to SIMS Martial Arts.
