School Management

Our experienced team is characterised by a strong sense of responsibility, a pronounced sense of duty as well as a high level of interpersonal skills.

Our students are at the heart of everything we do. At the same time, we are aware that a school can only successfully educate young people to meet the challenges of today’s world if it is run by a management that is based on clear conceptual, economic, organisational and social principles.

Below, all members of the school management are introduced in their respective mother tongue.
