BJJ Instructors


Dan Hewitt

I had always wanted to learn martial arts. It wasn't until I met Wendy (my wife) that I finally had the opportunity. I started training Karate under her Father in 2006 when he reopened the Mountain Warrior School of Karate. In 2009 my wife and I purchased the business from her parents. I recieved my Black Belt in Karate in November 2010.

I began training in Brazilian Jiu Jitsu in 2009.... and my passion for martial arts elevated to a whole new level! I received my Brown Belt under Professor Michael Chapman (Founder/Owner of Impact Jiu Jitsu Beaverton, OR) in July 2017.

I am proud to be the Head Instructor of all of our BJJ Progams/Classes (Kids, Teens, Adults, and Ladies)

Andrew Lakey

I started training Martial Arts in the mid 1980's , studying styles such as Japanese Jiu Jitsu, Karate and Judo. In the 1990's I trained Aikido, JKD, Boxing and Filipino martial arts. On a trip to Southern California while training Progressive Fighting Systems I was introduced to Brazilian Jiu Jitsu. At the time, there were no Brazilian Jiu Jitsu black belts in Oregon and very few places to train. I spent many weekends traveling to train with groups of JKD and Jiu Jitsu practitioners. That is the main reason it took me 20 years to get my blue belt. I received my purple belt in Jiu Jitsu from Impact Jiu Jitsu and my Coach Michael Chapman in 2014.

Sutter "Chainsaw" Johnson

I started BJJ at the age of 10. I had previously wrestled and played football but it wasn't until I found BJJ that I found my passion. I used to be very shy and BJJ cured me of that shyness. I started competing soon after my training began and have gone on to be the:

    2015 Oregon Subleague Chanpionships Gold Medalist
    2016 IBJJF Kids PanAm Bronze Medalist
    2016 Kids Worlds Silver Medalist in No-Gi and Bronze Medalist in Gi
    2017 IBJJF American Nationals Bronze Medalist
I am also the Assistant Instructor at MWAMA in all of the kids BJJ programs so that I can pass on that passion for BJJ to other kids. I love seeing the kids progression in their techniques and increase in their confidence. I have also found that by teaching the kids it has also helped me improve with my own growth in the sport.



All martial arts training should only be used to better ones self and as a path to higher understanding of ones self.  Martial arts should never be used with the intention of purposely seeking to cause harm to others.
