She worked for Maryknoll from 1989 to 2012.

She holds a masters degree in moral theology from Washington Theological Union and  honorary doctorates from Trinity Washington University and Alvernia University.  She is a lay woman, a mother of six and a grandmother.  She is author or co-author of seven books, including Oscar Romero: Reflections on His Life and Writings and St. Francis and the Foolishness of God.

She was one of the primary organizers of the April 2016 Conference on Nonviolence and Just Peace that was cosponsored by the Pontifical Council for Justice and Peace and Pax Christi International. The conference called on the Catholic Church to re-commit to the centrality of gospel nonviolence; proposed the World Day of Peace 2017 theme on nonviolence; and started the Catholic Nonviolence Initiative.
