Our Team

Our core team consists of dedicated professionals with broad experience in safety, self-defense, and personal development. We dedicate ourselves daily to supporting, inspiring, and empowering others.

Martin Kaya

I am Martin Kaya, and I work within the justice system, where safety plays a central role. With nearly 30 years of experience in martial arts and self-defense disciplines such as Wing Chun, Eskrima, Jeet Kune Do, and Silat. I have developed extensive knowledge of resilience and the conscious connection between body and mind.

My practical experience and personal development reinforce one another and together form the foundation of my approach.

I focus on sharing knowledge with young people and adults, with the goal of helping them become stronger, more aware, and more self-confident in everyday life.

Patrick Vos

My name is Patrick Vos, and loyalty and respect are the foundation of who I am. With a broad background in various self-defense disciplines, I have gained extensive experience that I am happy to use to support others.

For me, self-defense goes beyond technique; it is about discipline, self-control, and developing inner strength.

I train both young people and adults, with a focus on physical skills, self-confidence, and perseverance.

Lis Demarteau Vos

I am Lis, and I have a strong drive to contribute to society and to be there for people who need support. As an independent entrepreneur, I work daily on optimizing business operations in international organizations, focusing on structure, efficiency, and sustainable growth.

Within Sterk voor Elkaar, I focus on the business and organizational aspects, ensuring the association can function professionally and with a future-oriented perspective.

I enjoy contributing to a stable and well-organized association where people are given the space to grow in strength and self-confidence.
