This article describes the work of the Circle of Courage, a cross-cultural group committed to improving the cultural competence of organizations providing services to Aboriginal populations in a midsized city in Canada. Rather than concentrating on individuals' cultural competence, the Circle targets mainstream organizations. Many of its activities, therefore, require organizations to examine themselves and make systemic changes. Providing support to Aboriginal staff of mainstream organizations is a significant element of the Circle's initiatives. After an analysis of cultural proficiency--particularly at the organizational and systemic levels--the history of the Circle, its internal functioning, and its specific activities are described. The impact of the Circle's attempts to make systemic change is summarized.
