Ethnic nonprofit community-based organizations (CBOs) have played a crucial role in the social fabric of ethnic communities. Despite the importance of ethnic CBOs, limited empirical knowledge exists about these types of organizations. This study seeks to fill this gap by exploring how ethnic CBOs engage their target populations in stigma-associated services using a multidimensional cultural competence framework. A case study approach is used to explore how a Korean ethnic organization engages older adults in mental health services. The study provides an in-depth examination of the organization’s responses to the increasing need for mental health services for older Korean adults by providing culturally grounded services in a nonstigmatized environment. The study contributes to current literature by (a) using a multidimensional approach to examine community, organizational, and individual factors that influence mental health service use and (b) exploring how ethnic organizations consider these domains to serve older Korean adults.
