Our Mission and Purpose

The Columbia Union Conference exists to advance and fulfill the mission of the Seventh-day Adventist Church in the Mid-Atlantic United States. We provide administrative leadership, governance and support services to our conferences, ministries, healthcare networks, elementary and secondary schools, college and university. Above all, we assist and enhance the ministry of these organizations in sharing the three angels’ messages and preparing people—locally and globally—for Christ’s soon return.


The Columbia Union Conference serves as the regional headquarters for a cluster of conferences located in the eight states that comprise the Mid-Atlantic region of the United States. 

It was formally organized in 1907 and began operations on January 1, 1908. Headquarters were located adjacent to Columbia Union College in Takoma Park, Md., until 1980 when it moved to its present location in Columbia, Md. The first president was W.J. Fitzgerald. At the time of formation, the Columbia Union Conference consisted of 187 churches and 5,320 members. Today, there are nearly 800 churches and almost 140,000 members.

The Columbia Union, as it's often called, exists to coordinate the mission and work of the Seventh-day Adventist Church in the Mid-Atlantic United States. We provide administrative support to its eight conferences, two healthcare networks, 90 elementary and secondary schools, a health sciences college and a university. We facilitate and engage members and organizations in community services, mission work at home and abroad, evangelism, effective leadership and governance, strategic planning, and other mission-focused initiatives. We also support members by assisting with religious liberty issues, offering ministry training and networking opportunities and helping plan wills and trusts.

To keep members informed about the work of churches, conferences, schools, healthcare organizations and ministries within the Columbia Union, we publish the Visitor, a monthly news magazine; sponsor a news website; distribute email news updates; and maintain social media pages--Facebook, Twitter and YouTube
