The HALO Trust and The HALO Trust USA, Inc. are managed from HALO’s global headquarters in the UK. Each has its own board of trustees  but they work together to ensure that the charity’s strategy and decisions meet the needs of the vulnerable communities we serve, as well as our donors and staff.

We are enormously grateful to our trustees, all of whom are highly experienced professionals who share our commitment to protecting lives and give their time so generously.

“The work of HALO goes beyond saving lives; it restores hope, transforms communities, and lays the groundwork for sustainable peace and prosperity. I am deeply honored to have the opportunity to help advance HALO’s work clearing landmines and unexploded ordinance. America’s support for HALO is more important today than ever and I look forward to elevating this urgent work in the United States.”
