Our Story
Jiu Jitsu 101 is a modern martial arts academy that is deeply rooted in old-school martial arts philosophy. We honor the teachers that came before us, and we respect the martial code.
Our martial arts base and lineage is a combination of Combative Karate Jutsu (Kyokushin & Kokondo Karate), Japanese Jujutsu (Judo) and Brazilian Jiu Jitsu (BJJ).

The JOURNEY
to jiu jitsu 101
You might know us as KHJi founded in 1991 & later became the Asylum Combat Academy operating mainly in Portland Metro area of Oregon State & operated a few classes at a shared facility in Vancouver Washington since 2009.
In 2013, the main operations HQ moved from Portland, Oregon to Vancouver, Washington continuing to operate as the Asylum Combat Academy until March 2022.
In March 2022, my family and I decided it was time for a change, so we set off toward the Oregon Coast to embrace a slower pace of life, still dedicated to daily training. I brought my passion for martial arts with me to Rockaway Beach Oregon, training where I could, with anyone who wanted to learn. I wanted to take a new approach to my journey– one centered around community, wellness, family and empowerment of others. This is where the new chapter begins.
On October 1st, 2023, I established the Asylum Combat Academy Oregon Coast, moving it from Vancouver Washington to our current location. Taking guidance from my new mantra, it became clear a new name would be appropriate, so the Asylum Combat Academy would be changed to dba Jiu Jitsu 101, named for our location on the iconic highway 101 that runs in front of the school, and our commitment to basic principles (101).
We want to welcome everyone to our school and journey. Whether you are brand new to the martial arts and combat sports, or you are seasoned student with decades of experiences, we have a place for you– we all learn from each other and grow together.

CHIEF INSTRUCTOR
My journey,
My Martial journey began in the early 70s doing Karate, Judo and Japanese Ju-Jutsu. As a youth it had become the focal point of my life in every way guiding me through the toughest obstacles that face a young man providing me structure, discipline & a code to lean into when life struggles hit with unyielding force. The journey has also introduced me to countless others who greatly influenced my life course both on & off the mats leading me to my current mentors Professor Michael Downing and Master Pedro Sauer.
I have been a black belt Karate Jutsu & Japanese Ju-Jutsu instructor for going on 38 years and have been teaching Brazilian Jiujitsu for over 15 years. I currently hold a Blackbelt in Brazilian jiujitsu and continue to teach Brazilian jiujitsu under the guidance and mentorship of Professor Downing & Pedro Sauer for over 10 years and counting. I am honored and eager to continue my journey sharing my knowledge and experiences while continuing to grow personally with the next generation of martial artists here on the Oregon Coast and beyond.
"ALWAYS TRAINING ALWAY LEARNING"
My personal mantra: “STUDENT FIRST, INSTRUCTOR SECOND”
