Leadership Team

The overall operational responsibility of the school, in accordance with the School Articles of Association, rests with the School Director and not the Board of Trustees.

The Director shares strategic and pastoral initiatives, as well as operational review, with his Whole School Leadership Team, which consists of the Division Principals, the Head of Campus in Sindelfingen, the Business Manager and the Director of External Relations.  Each of them is tasked with the general management of his/her respective department as well as providing for smooth transitions from one department into another.

Meet the Director and the divisional leaders:

In the High School years it is essential that each child discover his/her ‘element’. This discovery then guides the subject and program choice process in the diploma years. Mary-Jane’s philosophy of education therefore centers on educating the whole child as an individual.
