 We teach Poekoelan Tjimindie Tulen, a traditional martial art brought to this country from Indonesia by Mas Goeroe Agoeng Willy Wetzel in 1956. It draws on the most effective elements of Judo, Kempo, Kung Fu and Karate. Since Poekoelan is a complete martial art, it’s much more than just self-defense. Students find well being and empowerment of body, discipline of mind and strength of spirit.


Tulen Center is dedicated to empowering its students. We nurture the body, mind, and spirit in a holistic environment. Through the course of your beginning training you learn 108 ways to defend yourself from threatening situations.

They have two kids and in their spare time enjoy hiking, camping and serving in the community.


“After checking out several martial art and self-defense classes, we chose Tulen Center based on its warm, personal approach. We have enjoyed getting to know the instructors and the art of Poekoelan. My son has gained a sense of pride since starting training at Tulen Center.”   – Happy Mom

Through an invitation from the HR department, we recently taught a three-part self-defense class at Dr. Martens USA HQ in Portland. Here is what they had to say about it:

 Dear Future Tulen Center Business Partners,Successful businesses create engagement through building a community within their workforce. The Tulen Center has been a key partner to Dr. Martens AirWair USA in fostering essential components of community. That of safety and well-being.The Tulen center conducted a series of training courses for our staff that combined lecture, storytelling, demonstration, and both physical and verbal participation. It was so satisfying to hear my fellow Dr. Martens’ employees talk about how the training increased their confidence and sense of empowerment. The trainings were a great value for the time. And, they were a lot of fun! I’d recommend the Tulen Center to any business looking to invest in the physical and mental well-being of their teams.Best,

Here are a few comments from some of the participants:

  • I feel more confident that I will be prepared in a self-defense situation.
  • By attending this class my awareness has gone to another level.
  • My favorite thing was learning how to defend against an attacker.
  • The teacher was wonderful!
  • I appreciated the combination of talk and action.
  • My favorite thing was realizing how much power we actually have, and how I can defend myself if I really need to.
