Scott’s expertise includes addiction, medication for addiction treatment (MAT) for substance use disorders and building well-functioning, interdisciplinary treatment teams. He has worked across the criminal justice system to implement MAT in jails and prisons as well as provided evidenced based interventions to reduce incarceration and recidivism.
Before joining HMA, Scott worked as a physician assistant with Spectrum Health Medical Group Center for Integrative Medicine where, in addition to clinical services, he provided expert consultation to social worker case review. He also developed pathways with insurance payers to identify and refer appropriate patients with the highest utilization to appropriate programs and treatment teams.
Dedicated to providing care to those most in need, he spent 10 years as lead physician assistant, providing primary and psychiatric care at a Federally Qualified Health Center in rural Washington.

Scott has also served as regular preceptor for physician assistant students, served as a member of peer review committees, and was the co-clinical lead for implementing electronic health records helping medical providers with the transition.
