Relatively little empirical and theoretical research in public management explores the roles of professional associations in collaborative governance and inter-governmental relationships. Drawing on network perspectives and social psychology literature, this study aims to bridge the gap by examining the case of the Los Angeles County Management Council (LACMC) and theorizing about the characteristics of inter-agency collaboration that is derived from local professional associations. Results from the qualitative analysis reveal five key themes: relational comfort and affect-based trust, autonomy and spontaneity in knowledge sharing, shared identity and group cohesion, enhanced system awareness, and informal accountability.
