The art of modern day Brazilian Jiu Jitsu was originally derived from the Japanese martial art of Kodokan Judo in the early 20th century, which was developed from a number of schools of Japanese Jujutsu in the 19th century by Kano Jigoro and one of his students Mitsuyo Maeda.

In 1916, 14-year-old Carlos Gracie watched a demonstration by Mitsuyo Maeda (aka Count Coma) and was inspired to learn the art. Gracie was accepted by Maeda as a student and went on to become a great exponent of the art. Ultimately, along with his younger brother Hélio Gracie, Carlos founded Gracie Jiu Jitsu (what we now refer to as Brazilian Jiu Jitsu or Jiu Jitsu).

Carlos Gracie Jr. followed in his father’s footsteps, winning numerous world championships and producing many world champion black belts. One of these notorious champions is Rigan Machado, now an 8th degree red/black belt. In 1988, Chris Haueter began his training in California under Rigan Machado. In 1996, Haueter became one of only a handful of Americans to be awarded with a black belt in Brazilian Jiu Jitsu, the “BJJ Dirty Dozen”.

Like the great instructors before him, Haueter has produced his own line of incredible Machado black belts, including owner and founder of Impact Jiu Jitsu, Michael Chapman (now a 4th degree black belt).


Impact Jiu Jitsu’s beginnings stem from Japan where in 1991, founder Michael Chapmanstudied “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.

Today, Impact Jiu Jitsu is the proud home to 46 Brazilian Jiu Jitsu Black Belts: Michael Chapman (4th degree); Armand Debruge (3rd degree); Cameron Apple, Keisuke Andrew (2nd Degree); Todd Betters, Eric Jetton, Matt Leech, Tommy Leisman, Woody Little, Dewey Nielsen, Richard Rangel, K.C.
