Organizations, like people, are susceptible to negative effects of trauma, including fragmentation, numbing, reactivity and impaired relationships. These effects in turn prevent staff from responding effectively to each other and to the people they serve. In this webinar, Dr. Kenneth Epstein of the San Francisco Department of Public Health outlines the Trauma-Informed Systems Initiative (TISI) which is working to make SFDPH a more trauma-informed, safe, and supportive work environment and system of care.
