In the year since Donna Bruce started working at the Baltimore public library's Penn North branch, she has connected more than 400 visitors to housing programs, food assistance and substance abuse recovery options and saved a man from dying of a drug overdose by administering the emergency treatment Narcan. Poverty is pervasive in the neighborhoods around the Penn North library, and many people come in simply looking for heat or shelter. Bruce is leading a team of "peer navigators" in the library system trained to provide trauma-informed engagement and support to the public. All navigators have personal experience with mental health challenges or substance abuse disorders and act as role models in the community. Peer Navigators is the first city agency program that owes part of its origin story to Baltimore's 2020 Elijah Cummings Healing City Act. The goal of the groundbreaking legislation is to help departments reckon with and change policies that have caused " and continue to cause " trauma, while charting a new path rooted in healing. The act mandates that city employees receive training, to gain awareness and learn how to help those who have been harmed. At the same time, agency leaders must evaluate their practices and procedures to determine if they are causing trauma and how to change those that are to better serve Baltimore's communities. Evidence shows the approach can improve social environments, decrease violence, and reduce other negative encounters.
