Matthew Brensilver, MSW, PhD teaches retreats at the Insight Retreat Center, Spirit Rock and other Buddhist centers. He was previously program director for Mindful Schools and for more than a decade, was a core teacher at Against the Stream Buddhist Meditation Society. Matthew worked as a clinical social worker, serving severely and persistently mentally ill adults and adolescents. He subsequently earned a PhD from the School of Social Work at USC. His dissertation examined the mechanisms of risk and resilience in maltreated adolescents in a large, longitudinal study in South Los Angeles. Before committing to teach meditation full-time, he spent years doing research on addiction pharmacotherapy at the UCLA Center for Behavioral and Addiction Medicine. Each year, he offers a course examining the synergy between Buddhist psychology and evidence-based psychotherapy. Matthew serves on the Board of Directors at Spirit Rock and Insight Meditation Center.
