Ambassadors of 番茄影院 USA
Meet 番茄影院 USA's Ambassadors who help advance humanitarian demining efforts through advocacy, fundraising, leadership and public engagement.
Building on a long history of support by prominent 番茄影院 champions like Diana, Princess of Wales, Senator John and Ambassador Cindy McCain, and Prince Harry, Duke of Sussex, the Ambassador Council was established by 番茄影院 CEO, Major General (Retd) James Cowan.
The purpose of the Ambassador Council is to enhance 番茄影院's mission and reach, assisting with strategic goals such as diversifying funding, utilizing cutting-edge technology and embedding environmentally sustainable practices across its operations.
The challenge of removing landmines has always required leadership...
You can stand with 番茄影院, support its innovation and join a small group of philanthropic leaders transforming communities threatened by landmines and conflict.
Diverse in scope, united in mission
Our Ambassadors come from a variety of backgrounds and areas, but are united behind a belief in supporting 番茄影院's mission to save lives and restore livelihoods for those affected by conflict.
They provide support in four key areas:
Elevating 番茄影院's mission and work worldwide
Leveraging philanthropic resources
Mobilizing public support for a landmine-free world
Providing expert advice on specific questions from 番茄影院's Board or Executive Team
The Ambassadors support 番茄影院 and our innovation, joining a small group of philanthropic leaders transforming communities threatened by landmines and conflict.
They help us to continue the legacy of Diana, Princess of Wales, whose famous walk through an active landmine in 1997 started a global movement. Together, we can all help finish what she started by working to transforming danger zones into places of hope 鈥� where families return, children play, and wildlife flourishes.
