Sheena Friesen, PhD (she/her), is the attending psychologist for the Child Program on the inpatient Psychiatry and Behavioral Medicine Unit at Seattle Children’s Hospital and Assistant Professor in the Department of Psychiatry and Behavioral Sciences at the University of Washington.

Dr. Friesen received her Ph.D. in School Psychology from the University of Washington in Seattle, WA. She completed her pre-doctoral internship training at Johns Hopkins School of Medicine and Kennedy Krieger Institute and went on to complete her postdoctoral fellowship in acute care and clinical psychology at Seattle Children’s Hospital.
I am a trained Behavioral Scientist with a PhD in Health & Human Performance. The main goal of my work is to reduce substance-related harms and improve quality of life for people experiencing problems related to their substance use. I work closely with community members who use drugs to inform my line of research and address key needs identified. My primary appointment is at the Harm Reduction Research and Treatment (HaRRT) Center within the UW School of Medicine and hold an Affiliate Faculty appointment within the School of Public Health. My aim is to adapt, refine, and disseminate harm reduction programs through digital health interventions to empower individuals and ameliorate substance-related harms.
Dr. Walukevich-Dienst (hear my name) is a licensed clinical psychologist and an Assistant Professor at the University of Washington.
Her research is focused on identifying psychosocial and contextual factors associated with alcohol and cannabis misuse and co-use among young adults, including social influences (e.g., romantic partners, use partnerships), affect management motives, co-occurring mental health concerns, and high-risk substance use events and contexts.
Dr. Walukevich-Dienst aims to leverage this information to develop and test innovative, technology-informed prevention and intervention efforts to disseminate in real world settings.
She also provides psychotherapy to patients at the University of Washington’s Outpatient Psychiatry Clinic and provides supervision and training to psychology graduate students and psychiatry residents in Cognitive Behavioral Therapy.
