Marc MacYoung


Marc MacYoung has studied numerous martial arts since the age of ten, including Wing Chun, Eskrima, Silat, Karate, and Five Family Gung Fu. He administers several self-defense programs for the general public and has taught law at law-enforcement agencies and military sites around the world. Marc Animal MacYoung is an American survivalist author and martial artist. Initially known best for his street-violence survival books, MacYoung later went on to write personal safety / self-defense books and make instructional videos.


Marc MacYound developed Dango Jiro. Dango Jiro is not a martial art. And despite the Japanese name, it is neither a traditional nor ancient. Nor is it a modern fighting system, a combat system, a reality based fighting system or a macho streetfighting style. Dango Jiro is a training system.


It is not what fighting style someone knows that makes him competent at physical conflict. It is his ability to successfully and appropriately apply his skills, under stressful conditions. That, not knowing a martial system is what defines competence. Competence isn’t about how many (or what) techniques you know. It’s about Git-R-done. It is you and your skill, not the system, that will be the source of your success in a physical conflict.

Amos Lee Parker Shihan (In Memorial)


Amos Lee Parker was born December 12, 1936 in Houston, Texas. He is the 7th of 16 children.

At age 18, Amos joined the United States Navy and it is here where his life in Aikido begins. Amos spent 35 years training in Japan with Kiyoyuki Terada Hanshi, 10th dan.

Amos began his full-time study of Yoshinkan in 1962 while a member of the United States Navy in Yokosuka-cho, Japan. Upon his retirement after 20 years of service to his country, he remained in Japan for another 20 years to further his own development and understanding of Yoshinkan Aikido.


Some of his career highlights include:

• Highest ranked non-Japanese instructor in Yoshihan Aikido


• Highest ranked member of Terada Honbu Seiseikai


• Highest ranked Yoshinkan Aikido instructor in the United States


• Received the title of Shihan in 1986


• Received the rank of 8th dan in 1995 and 9th dan in 2009


• Served as a presiding judge at several Enbutaikai


Parker Shihan had great technical skill and was a stickler for the fundamentals.  His voice always reminded me of Jazz from the Transformers (cartoon not movie).

I remember if my stance wasn’t right he would say “Kasey, too tall, too tall”.  Or if someone just wasn’t getting it, he would say in that very distinct voice, “Do you even know Aikido?”

He was a very good teacher and he will be sorely missed.
