Blase Bonpane is Director of the Office of the Americas (based in Los Angeles, California) which he co-founded with his wife Theresa in 1983. His attention has been primarily on human rights and identification of illegal and immoral aspects of domestic and foreign policies of the United States.

Bonpane served as a Maryknoll priest in Guatemala and was assigned by the Cardinal of Central America as National Advisor to Centro Capacitacion Social, a center for university and high school students working in the field with indigenous people on matters of health, literacy and labor organization. He was expelled from that country in 1967 in the midst of a revolution. (Washington Post, February 4, 1968, "A Priest in Guatemala.")

He played a significant role in the historic dialogue in Latin America between Christianity and Marxism. (Guatemala: Occupied Country, Eduardo Galeano, Monthly Review Press, 1969) Blase Bonpane led investigative delegations to Nicaragua, Cuba, Mexico, Panama, Honduras, Costa Rica and Peru. He traveled through the conflictive zones of Chiapas, Mexico together with Bishop Samuel Ruiz on a series of peace missions and served on the board of SICSAL, a hemispheric ecumenical secretariat based in Mexico City. He also participated in peace missions to El Salvador, Colombia, Ecuador and Iraq. (See the Blase Bonpane Collection, Department of Special Collections, UCLA Research Library; Collection 1590).
