Impact Jiu Jitsu’s beginnings stem from Japan where in 1991, founder Michael Chapman studied “Shooto” or Shoot Fighting. When Michael returned to Oregon in 1993, he brought with him a passion for ground fighting. At the time, there was little known locally about Brazilian Jiu Jitsu. Michael pulled together training partners and they began to learn what they could through books, videos, and seminars with Brazilian Black Belts such as Rickson Gracie and Rigan Machado.
In 1997, Michael joined the Machado family when Black Belt Chris Haueter presented him a purple belt—Michael’s first colored belt. In 1998, Impact Jiu Jitsu was opened (known as Beaverton Straight Blast Gym until 2006). Chris Haueter awarded Michael with his Black Belt in 2004.
Since opening Impact Jiu Jitsu in Beaverton in 1998, Michael has been joined by many other amazing Jiu Jitsu athletes; some of whom followed a similar path to his as local pioneers in the sport.
Dewey Nielsen (Black Belt) and Matt Leech (Black Belt) joined the Impact Jiu Jitsu family in 2003 when they opened Impact Jiu Jitsu in Newberg. Dewey and Matt began their pursuit of Brazilian Jiu Jitsu years before, training in smaller facilities—from Matt’s garage to mat space in a local health club.
