Drawing from decades of experience in psychology and frontline mental health services, Dr. Tsemberis shares the journey that led him to challenge the status quo of homelessness treatment—shifting from a "treatment first" approach to one that prioritizes permanent housing without preconditions. From his early days at Bellevue Psychiatric Hospital to founding Pathways to Housing, Dr. Tsemberis witnessed firsthand the systemic gaps and human costs of policies that deny housing to those not yet "compliant" with treatment. Through compelling stories, research-backed results, and global replication efforts, this episode explores why Housing First isn’t just effective—it’s a matter of human dignity. Listeners will also hear his thoughts on workforce needs, replication of successful models like SMC's Homeless Services Certificate Program, and why shared public vision is essential to ending homelessness.
