Owner JD Olsen, known respectively as Shidoshi Olsen, is a high ranking martial artist with over 24 years of teaching experience.

Some of his numerous rankings and areas of expertise include: 4th Degree in Aikido, Karate, All Japan Submission Fighting, Zentai-Jitsu, Modern Kali, 1st Degree in Tae Kwon Do, Submission Arts Wrestling (SAW), Purple Belt in Brazilian Jiu-Jitsu, Intermediate Level 1 Filipino Martial Arts, Beginner level 4 Jun Fan Jeet Kune Do, and Orange Prajoud in Thai Boxing.

Shidoshi Olsen began his martial arts training at age five. Starting with Tae Kwon Do, he quickly fell in love with all things martial arts. The training of kicks, punches and forms became a daily routine and Shidoshi Olsen quickly rose through the ranks. However, after earning his first black belt, he was forced to switch styles due to his family moving.

Starting over in a form of karate called Wado Ki Karate, Shidoshi Olsen again worked his way up to purple belt before having to switch styles yet again. With just his mother and himself, Shidoshi Olsen was able to put in the time to earn another Black Belt in Shorei Ryu Karate.

Next was a major shift in Shidoshi Olsen's life as he entered the U.S. Air Force and was going wherever the military would take him. His first assignment was to Rapid City SD and while there Shidoshi Olsen found the art of Ninjitsu. Training under the Bujinkan, he was able to work his way up the rank of green belt. After that the military answered Shidoshi Olsen's dream and he was sent over to Japan.

While in Japan he was introduced to Progressive Martial Arts Black Belt AJ Weimer and began regular classes, as well as volunteering to help with any testing or demos possible. Staying dedicated he was able to earn Black Belts in multiple martial arts (Aikido, Kali, and Jiu-Jitsu) in 2003.

In 2003, Shidoshi Olsen opened his first martial arts school, while teaching on Yokota AB.

In 2004 the military reassigned Shidoshi Olsen and his family to Sumter SC. It is here where he began teaching on Shaw AFB, then opening his first off base location Keishidojo Martial Arts & Fitness Center. It has been here ever since, and has been the hosting place for seminars, tournaments and countless other events that have had an impact on the local community.

Keishidojo has hosted seminars including:

  • Martial Arts Unlimited founder A.J. Weimer

  • Sifu Ron Balicki

  • Guro Diana Lee Inosanto

  • Professor Helio Soneca

  • MMA fighter Derrick Kennington

There has also been countless in-house seminars to include our own specialized women's self-defense course called "BACK OFF!", youth bully-proof seminars, karate competition seminars, and sword seminars.

We have also hosted a fair amount of in house tournaments with the most popular being our own BJJ/grappling absolute tournament.

Determined to get even better, Shidoshi Olsen has become an affiliate member under Sifu Ron Balicki and his Martial Arts Research System and Professor Helio Soneca with his Brazilian Jiu-Jitsu program, with Mike Martelle and his Grizzly Gym which trains the Submission Arts Wrestling program, RCJ Machado Brazilian Jiu-Jitsu, and most recently Sensei Erik Paulson's Combat Submission Wrestling.

Shidoshi Olsen has started training again under these masters, working to obtain another Black Belt. He continues to work to advance himself and to provide his students with nothing be the very best in martial arts and self-defense training.

Shidoshi Olsen takes his martial arts/self-defense training very seriously and wants to ensure all his clients know they are getting the very best he has to offer.
