Connecting the World's Chiefs of Staff

Chiefs of Staff are the indisputable gatekeepers to the world’s leaders and their influence is increasing. They help leaders execute strategy and manage virtually all the interactions between the principal and stakeholders.

The Chief of Staff Association puts you in the company of the world’s most connected, innovative and influential gatekeepers.

Our members are Chiefs of Staff across governments, militaries, royal households, corporations and family offices. We convene discreet sidebar events during global multilateral meetings, advancing ‘track two’ diplomacy, particularly between the public and private sectors.
