The Survivors of Tragedy Outreach Program (S.T.O.P.) is a coalition offering support, outreach, and lived experience from individuals directly impacted by and responding to terrorism and mass violence. We are an international network of survivors and nonprofits that have come together for advocacy, prevention, and peer support to promote long-term recovery and resilience to triage and address the multi-layered impacts of targeted violence and preventable mass-scale tragedies.
