We build relationships with local organizations that are caring for people in need and create opportunities to serve. Our volunteers are locals, Expats, migrants and more People like you and me - we build bridges between us.

Sign up for a project and discover that the things you love to do can make a difference in someone else’s life. Step by step our vision is to transform the face of the city. Lots of people doing small things will bring change. Your part matters.

We have projects in different parts of Köln. Our dream is to serve in every neighborhood. STC is one of the fastest growing movement. STC started in Brussels in 2005 with a week of volunteering and is now active in 65 cities around the world!
