As a non-profit organization with a focus for social impact we are being supported and advised by very engaged co-thinkers and hands on workers! Since its founding year CHORUS has grown into an initiative with a core group of high-class professionals.

We connect and work in a dynamic world, therefore we adopt the ‘team-of-teams’ appraoch. Our core group consists of a board, master team and whatever team is effective. Mostly the teams are formed by advisors and inspirators, who assertavily connect with the community. The best initiatives with the most energy, in line with our vision, get full support of our core teams!

Our trade: Find and connect people that excel and strive to work for the vision of People who have the heart in the right place. These hearts beat for Counter Social Engineering now and in the futuer! Therefore we provide guidance to our younger generations in practicing their right to being self-determined individuals!
