Mark Duncan, MD

Personal Statement

I have pursued a career at the intersection of mental health and primary care, training in both family medicine and addiction psychiatry.  I currently practices in various integrated care settings as a consulting psychiatrist and in the outpatient adult psychiatry clinic.  I am also the co-medical director for the University of Washington Psychiatry and Addiction Case Conference (UW PACC) which is an online learning collaborative to help community providers across the state improve their psychiatric and addiction clinical skills.  My area of interest is focused on bringing addiction treatment to primary care settings.  I also spend a significant amount of time training both family medicine and psychiatry trainees and fellows on integrated treatments for substance use disorders.
