The Klax School team
The staff at Klax School is international, professional, and cosmopolitan. Our teaching staff are trained subject teachers, educators, and social workers from Germany and many other countries.
Here, people from different cultures work together successfully and happily. This attitude is noticeably reflected in everyday school life. Our teachers share their experiences and knowledge. This way, our students grow up with a sense of cosmopolitanism.
