National Coalition for Dialogue and Deliberation


An international process arts organization headquartered in the United States.


The National Coalition for Dialogue & Deliberation (NCDD) actively promotes learning and collaboration among practitioners, public leaders, scholars and organizations involved in dialogue, deliberation, and other innovative group processes that help people tackle complex issues.

Our membership includes more than 1,270 organizations and professionals from across the U.S. and 39 other countries. The NCDD website offers literally thousands of resources and best practices, and we keep in touch monthly with 20,000 people in  public engagement and conflict resolution.

Our national and regional conferences, online programs and resources, and numerous collaborative projects provide opportunities for members of the dialogue and deliberation (D&D) community to share knowledge, collaborate, and build relationships. NCDD provides the infrastructure needed in this community so we can work together to increase our individual and collective impact.

NCDD was formed in 2002 in response to a clear need for more learning and collaboration among those who approach D&D  from a variety of disciplines (public policy, social work, communications, education, social justice, etc.). The Coalition was a result of the first National Conference on Dialogue & Deliberation, held near Washington, DC in October of that year.
