ACG Headquarters

During the first week of February 2005, the American College of Gastroenterology moved into its new national headquarters building located in Bethesda, Maryland. In recognition of the continued outstanding growth in membership and programming, the move is designed to permit the College’s administrative staff to better serve the needs of the organization and its members. The new space provides a significant upgrade in the amount of work-space and will permit the College to meet its administrative staffing needs for the foreseeable future.

The move to increase administrative capacity is an outgrowth of the review of the College’s capabilities and resources that began in 2001 with then President Edgar Achkar’s appointment of a strategic planning committee and culminated with the ratification of the ACG Strategic Plan in 2002. The College’s Board of Trustees believes all members will benefit from an increased level of service and new and exciting programs that build on the ACG’s unique role as champion of clinical gastroenterology.
