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.
