This online course emphasizes that Indigenous clients in North America often carry complex, intergenerational trauma rooted in colonization, land displacement, broken treaties, residential schools, forced adoptions, and ongoing crises such as opioid-related deaths, suicide, and the epidemic of murdered and missing Indigenous women and children. For mental health professionals—particularly those from the dominant culture—this context is not background information but central clinical material. Indigenous communities are frequently underserved, and there are not enough culturally informed Indigenous therapists to meet demand. As a result, non-Indigenous clinicians must be willing to step into this gap responsibly, with humility and a deep commitment to trauma-informed, culturally responsive care. Understanding complex grief, attachment trauma, dissociation, and implicit memory—especially through modalities like EMDR adapted for complex trauma—is essential, but must be grounded in cultural awareness.
