Sandy Hook Promise (SHP) envisions a future where all children are free from school shootings and other acts of violence. As a national nonprofit organization, SHP’s mission is to educate and empower youth and adults to prevent violence in schools, homes, and communities. Creators of the life-saving, evidence-informed Know the Signs prevention programs, SHP teaches the warning signs of someone who may be in crisis, socially isolated, or at-risk of hurting themselves or others and how to get help. SHP also advances school safety, youth mental health, and responsible gun ownership at the state and federal levels through nonpartisan policy and partnerships. SHP is led by several family members whose loved ones were killed in the tragic mass shooting at Sandy Hook Elementary School on December 14, 2012.
