Leadership & Governance

L’Arche International is responsible for the leadership for the federation of L’Arche communities worldwide. It does this by ensuring the mission of L’Arche is lived and resourced and throughout the federation. In addition to this work, it also provides leadership and financial support to L’Arche communities in developing economies and those in countries without a L’Arche leadership structure. For further information about our strategy and financial overview go to our Annual Summary 2019.
