Andrew is a acting assistant professor in the Department of Psychiatry at UW and attending psychologist at Seattle Children’s Hospital working both in Mood and Anxiety Program and on the Consultation Liaison service.
He is currently engaged in research related to substance use, primarily cannabis use, and loves working with kids and adolescents with conduct and substance use concerns.
He was most recently faculty at the University of Colorado Anschutz where he worked as a CL psychologist in primary care at Children’s Hospital of Colorado. He completed his graduate training at the University of Alabama, a T32-funded postdoctoral fellowship focused on cannabis and nicotine use at the University of Alabama at Birmingham, and a clinical fellowship at Children’s Hospital of Colorado specializing in primary care psychology.
I am a licensed clinical psychologist in the University of Washington’s Department of Psychiatry and Behavioral Sciences, working in adult inpatient care within the Center for Behavioral Health & Learning. I bring specialized training in serious mental illness, inpatient psychiatric care, serving populations with comorbid substance use and/or medical complexity, and enjoy working collaboratively within multidisciplinary teams to optimize patient-centered care. I also bring a global public health background in improving service delivery and access in low-resource settings across Africa and Asia.
I graduated with a PsyD in clinical psychology from the University of Denver, after completing my pre-doctoral internship at Mt. Sinai/Elmhurst Hospital in New York. During this internship, I completed rotations in the adult inpatient unit, the child partial hospitalization program, psychiatric emergency room services, and the consultation-liaison psychiatric service, serving a patient population that is among the most ethnically and culturally diverse in the world. I am dedicated to providing high quality, empathetic, and innovative interventions to our inpatient population.
As a child and adolescent psychiatrist at the Child Study and Treatment Center, I am deeply inspired by the resilience of the youth we serve and by the collaborative spirit of our multidisciplinary teams. My work is grounded in curiosity, compassion, and respect for the complex systems that shape young people’s lives. My approach integrates evidence-based psychopharmacology with developmental and trauma-informed care, while always centering around the individual’s unique story and strengths. I value the relational and systemic dimensions of psychiatry: the interplay between family, community, and policy that influences recovery and growth. The multidisciplinary, relational model at CSTC reflects these values and continues to shape how I think about psychiatry: not only as a science, but as a deeply human endeavor.
My research and clinical interests include third-wave, cognitive-behavioral interventions for adolescents and young adults, family-based and parenting-related support for families of youth engaging in risky or challenging behavior, suicide prevention, prevention of child maltreatment, increasing equitable access to evidence-based services, and effective collaboration with clients who have been labeled as “resistant” by prior treatment providers.
