A multicultural team with solid mission experience

Cornerstone is run by a dedicated staff of WEC mission workers who feel called to the ministry of training people to be representatives of Christ in cross cultural mission work. Though all are well qualified for their specific jobs, staff members do not receive a salary but are supported by their churches and support groups. Because of this, college fees can be kept to a minimum.

The college is led by a leadership team: Elizabeth Stewart (Principal), Michael Eijgenraam and Ingeborg Till. The staff and leadership team are accountable to the Cornerstone Board.
