Officially recognised, privately supported

The International School Solothurn was launched by the Solothurn Economic Business Development Agency and established as a public limited company. ISSO AG is supported by renowned Solothurn companies. Additional partners who wish to be actively involved in shaping the educational infrastructure of the Canton of Solothurn, are always welcome.

Currently the Board of Directors is composed as follows:

  • Josef Maushart, President of the Board of Directors, Strategic Management
  • Jane Melmuka, Vice-President, International HR & Organisational Structures
  • Esther Luterbacher Graf, Marketing & Networking
  • Sonja Krapl, Supervision, Pedagogy und School Supervision
  • Hanspeter Kocher, Finance & Controlling
  • Dr Miriam James, Parents’ Perspective

One team. One spirit.

The ISSO teachers and supervisory staff, as well as all of those involved behind the scenes, see themselves as part of a team. This is particularly important because the different parts of our school closely work together, and because students and teachers know each other and repeatedly come across each other in their daily routines.
