Comprehensive multicultural organizational development (MCOD) is increasingly necessary in human services agencies. This article presents results from an exploratory study that identified challenges and solutions to MCOD, against the backdrop of daily realities of agency life. The author conducted interviews with 20 consultants and 20 practitioners experienced in MCOD. Qualitative analysis revealed four challenges -- socioeconomic environment, organizational dynamics, conceptualization of the change effort, and consultant competence; and four solutions -- collaborative environmental relations, leadership development, assessment and planning, and consultant selection. Results suggest the complexities of MCOD and ways that human services agencies can sustain such efforts.
