Our Team

The Crop Trust is a relatively small organization with a big mission. With about 45 staff members, the Crop Trust team have broad talents and exceptional drive. In addition to our full-time staff, we are supported by an active Executive Board, Donors' Council, Finance and Investment Committee as well as senior consultants who bring decades of expertise from across the world of crop diversity conservation. Of course, we could not carry out the work of global crop diversity conservation without our countless partners and supporters worldwide.
