Meet the Team

TVS Trustees and Committee members are all experienced professionals who have spent a lifetime working in education or children’s services. Trustees are all actively involved with TVS and regularly visit Tyume Valley at their own expense. TVS’s administration and overhead costs are therefore extremely low.
