The purpose of this descriptive multiple case study was to explore how counselors implement multicultural and social justice counseling competencies (MSJCC) when providing therapy to Black, Indigenous, and Womxn of Color. This study was informed by critical theory and intersectionality theory to capture the complex dynamics of identity and power through semi-structured interviewing, observations of archived counseling sessions, review of archived client case records, and administration of the Multicultural Awareness, Knowledge, and Skills Survey–Counselor Edition–Revised (MAKSS-CE-R), and the Social Justice Scale (SJS). The six doctoral student co-researchers provided rich portrayals of their experiences implementing the MSJCC, the role of identity, and the impact of power relations. Data revealed one overarching theme (the omnipresence of cultural humility), five themes (learning is a process, it starts with me: the catalyst of self-awareness, this is my identity, understanding clients in context: attending to power and intersectionality, and social justice is awareness: advocacy is intentional and active), and eight corresponding subthemes. Co-researchers provided insight into their experiences of barriers, oppression, resilience, and advocacy. Implications and conclusions from this research provide recommendations for mental health counselors, education programs, and research.
