“I am a licensed clinical psychologist and Professor in the Department of Psychology at Washington State University. I also hold affiliate faculty positions in both the Department of Psychology and the Department of Psychiatry and Behavioral Sciences at the University of Washington where I also codirect of the Harm Reduction Research and Treatment (HaRRT) Center at UW Medicine’s Harborview Medical Center. I have been involved in substance use research, assessment and treatment for over 2 decades and have disseminated this work in over 60 book chapters, abstracts and peer-reviewed articles. Using a community-based participatory research approach, I work with multidisciplinary research and clinical teams, community-based agencies, traditional Native health professionals, and people who use substances to codevelop, evaluate and implement interventions that aim to reduce substance-related harm and improve quality of life for people who use substances and their communities. I am also a mother, a wife, a sister and a daughter embedded within families affected by the intergenerational experience of trauma, addictive behaviors and substance use disorder. I attended my first 12-step meeting when I was 16, and my families’ and my own lived experiences drive my desire to reduce the stigma of addictive behaviors and meet people where they are at in all aspects of my work.”
