Be the change that you wish to see in the world.

- Mahatma Gandhi


Our non-profit organization is dedicated to empowering young people to make a positive impact in their communities and beyond. We believe that by providing youth with the tools, resources, and support they need, we can help them to become active, engaged citizens who are committed to making a difference in the world.

We work with youth in a variety of ways, including writing and implementing youth-centered projects, organizing workshops and training sessions, and providing mentorship and support. Our focus is on providing young people with the skills and knowledge they need to lead and participate in initiatives that promote social change and positive impact in their communities.

Our doors are open to anyone interested in joining our growing community. As a Trium member, you’ll have exposure to a vibrant network along with a wealth of knowledge and experience we’re happy to share! Our community is tight-knit, but incredibly welcoming. 

As a member of our team, you will have an opportunity to participate in Erasmus+ youth exchanges and training courses across Europe, learn about applying and implementing projects for EU and local funds, work with youth and children through creative workshops and games, work on different events and more.

We believe that one of the key factors of long-term success is the cooperation not only with the members within the association but with partners. We bring our expertise, experience and skills in order to achieve the goals for the benefit of the community with joined forces.

The cooperation is always transparent where we cherish equality, according to which each member has the right to express their point of view and the point of view of the organization they represent.

We have a strong commitment to our community and partnerships and always strive to meet our social responsibilities. One of our goals is creating new partnerships and nurturing existing ones.

We welcome any youth organization, schools, and individual that wants to join us in this mission, and we encourage you to get in touch with us to learn more about how you can get involved. Together, we can make a difference and empower the youth to become the change they want to see in the world.
