Founded in 1914 by 50 chamber administrators who met in Cincinnati, the Association of Chamber of Commerce Executives (ACCE) began as the National Association of Commercial Organization Secretaries (NACOS). "Secretary" was a common term for a chamber executive back then.
NACOS was headquartered in Washington, D.C. and had 176 members. Ten years later membership exceeded 1,000. In the 1920s, NACOS developed the Chamber Institute program which provided professional leadership and guidance to members. In 1948 NACOS officially became the American Chamber of Commerce Executives, and in 2014 ACCE was renamed to better describe its mission and character: the Association of Chamber of Commerce Executives.
Today, ACCE is headquartered in Alexandria, Va. and represents 1,300 chambers employing 7,000 staff throughout North America.
