Doctor of Ministry Program

St. Mary’s Ecumenical Institute’s Doctor of Ministry Program develops skill in appropriate ministerial research, attends to your personal and spiritual growth, and culminates in a summative doctoral-level ministry project. The program roots ministry in the mission of God, the ways God is working in your context, in your ministry, and in you. Whatever your theological tradition, denominational identity, or vocational setting, you will find space to grow in the company of extraordinary faculty and engaging colleagues. (Fully accredited by the Association of Theological Schools and the Middle States Commission on Higher Education.)
