Our open and constantly growing community that co-shapes our ideas, approaches and learning formats is the heart of horizontal school.


Our facilitators practice what they preach. They are practitioners in various fields such as civil society, organizational development and sustainability, coming from different cultural and geographical backgrounds. Their role is to empower, listen and convey competencies, as well as to share their own experiences, good practices and failures.
