Peggy is Chair of Synergos, a global organization helping solve complex issues around the world by advancing bridging leadership, which builds trust and collective action. Drawing from her experience living and working in Rio de Janeiro as a young woman, she realized that the people most affected by adverse living conditions also have the greatest energy and motivation to solve their problems. The resources they lack are connections to the economic and political realms where necessary changes can affect whole communities.

Marilia helps lead Synergos' Philanthropy program, including the Global Philanthropists Circle, a community of leading philanthropic families and social investors using their time, influence, and resources to fight poverty and social injustice in their own countries and around the world. She is also the founding partner of CARE Enterprises Inc., a for-profit subsidiary of CARE focused on creating gender justice through impact investment.
