Governance and management


Officially incorporated in 1960 by Protestant churches, IMA World Health serves as an ecumenical membership agency representing nine faith-based organizations. Our mission to serve the most vulnerable is grounded in our belief that we are stronger together than we are alone.  Members gather annually for a Members meeting to provide ultimate governance and oversight of IMA in electing its Board of Directors, affirming the agency’s chief executive, and funding and collaborating on IMA programs. Together, IMA and our Members share resources, collaborate on projects and share a common goal of advancing health and development through faith networks.

Members are:
  • Adventist Development and Relief Agency
  • American Baptist Churches USA
  • Christian Church (Disciples of Christ), Week of Compassion
  • Church of the Brethren
  • Episcopal Relief & Development
  • Lutheran World Relief
  • Mennonite Central Committee
  • Presbyterian Church (USA)
  • United Church of Christ
