This report describes six organizations’ efforts to become more trauma-informed, based on 69 interviews with staff and other stakeholders in 2017. These six organizations were selected to participate in a pilot demonstration as part of the Advancing Trauma-Informed Care (ATC) initiative led by the Center for Health Care Strategies and funded by the Robert Wood Johnson Foundation. Through this initiative, these organizations received grant funding and participated in a two-year learning collaborative allowing them to share insights with each other and receive technical assistance from national experts.
