David and Marilyn Graffenberger have been missionaries with OMS International since 1963, serving first in Haiti. In 1979 they joined the homeland staff at OMS International headquarters in Greenwood, Indiana. David coordinated overseas operations as director and vice president of Field Ministries (now International Ministries). Marilyn served in the Field Ministries office and then as assistant treasurer until they began their present assignment in 1988.

Until 2005, David was the International Director of the Every Community for Christ (ECC) ministry, the major evangelism and church-planting initiative of OMS International. This form of intensive evangelism involves small teams of two to six men or women assigned to a specific area or group of people in their own country. The goal of each team is to lead people to Christ, establish them in their Christian faith, organize them into local congregations and train them to multiply more churches.

More than 450 ECC teams are currently ministering in 41 countries. Dedicated missionary men and women serve these teams as Shepherds, giving oversight, encouragement and accountability to the team coordinators and team leaders through periodic visits, correspondence and prayer.

From 1993 to 1998 David and Marilyn gave leadership to the OMS-CoMission teams of missionaries in Russia, Estonia, and Eastern Europe. David was Field Leader in Russia from 1998 to 2000. Marilyn was the OMS Russia Field Treasurer from 1993 to 2001.

The CoMission teams worked in 12 cities helping train teachers to teach a curriculum of Christian ethics and morality in the public schools, lead Bible studies, and train Russians, Belorussians and Estonians as well as others to do the same. Follow up continues with trained national teachers and/or ECC teams in many of these cities.

David serves on the board of the Moscow Evangelical Christian Seminary as well as a seminary board in Central Asia. He is also a member of the International Ministries Advisory Council of OMS International and the Into Africa Planning Committee of OMS South Africa. Marilyn assists David with the ECC ministry, giving particular attention to the financial area.

The Graffenbergers make their home in Albany, Oregon, between overseas visits. They have one son, Brian, who lives in Oregon with his wife, Susie, and their two teenage children, Levi and Kirsti.
