Welcome to Tulen Center


Welcome to Tulen Center!

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.

Learn moves to keep yourself safe. Practice reacting quickly and calmly to protect yourself and your loved ones. Increase your peace of mind. Build self-confidence in all areas of your life. Gain coordination, muscle memory, strength, and all around good health.

Anyone can train Poekoelan. We specialize in individualizing our programs for your needs, in a comfortable and welcoming environment.

About the Students: Our students are just like you. They range in age from 4 to 64. They are moms and dads, elementary, middle and high school students and young adults. We have musicians, baristas, professionals, artists, IT experts, retailers and teachers. Some people start training with us to get in shape while others want something new and different in their workout. Tulen Center is a diverse place where students are included and accepted. We come together to support one another to be our best and highest selves. Tulen Center is a safe and loving place.

About the Owners: Goeroe Silvia and Goeroe Jeff have been training in Poekoelan for over twenty years and both have earned the rank of 5th degree black belt. They have trained hundreds of students and guided many to achieve their goal of black belt. With patience, discipline and love, they help shape their students’ characters and hone their martial arts skills. 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

Self Defense Classes for Property Management Companies

As part of our mission to reach out to the community, our instructors are brought in to help teach corporations and organizations self-defense techniques and empowerment. These courses are usually taught during lunch and focus on basic techniques to teach individuals to be more aware of their surroundings, how to use their voice and basic self-defense techniques to deal with worse case scenarios. The short courses help not only help establish confidence when dealing with difficult situations, but also helps establish team building in a safe environment with experienced instructors.

Here’s what Dalton Management had to say about us:

To whom it may concern,

The Tulen Center taught an amazing personalized self-defense class to 35 people in our company. Mas Goeroe Silvia Smart, 6th degree black belt, met with our Safety Committee ahead of time to learn what was important to the group and then built the self-defense class around those ideas.

In property management we are often in situations where we are alone with people we don’t know in empty apartments or working alone in offices. It was helpful to have a class geared specifically towards dealing with these scenarios as well as tools that our team can use in other areas of their lives. Silvia Smart and Eric Gorman gave us positive, encouraging instruction while boosting our self-confidence.

Our group ranges in age from 26 years old to 65 years old with varying degrees of physical limitations and disabilities. Some people were nervous about practicing in front of co-workers and concerned about their physical abilities, but quickly warmed up to the relaxing atmosphere at the school. The instructors encouraged questions and participation and led the class in a way that kept the team interested and involved. It didn’t take too long before people were firing off questions and getting excited to participate in the training. As a supervisor, it was great to have the entire team in one room without having to isolate certain people by physical ability.

In the end we had an incredible instruction session and a memorable team building experience. Silvia is already working with us to help build on the class for next year.

I am thankful for the instructors at the Tulen Center and the instruction that they offered to our company.
