Sandy Hook Promise is a national nonprofit organization founded and led by several family members whose loved ones were killed at Sandy Hook Elementary School on December 14, 2012. Specifically, Mark Barden, father of Daniel, who was killed in the Sandy Hook Elementary shooting and Nicole Hockley, mother of Dylan, who also was killed in the Sandy Hook Elementary shooting.Based in Newtown, Connecticut, our intent is to honor all victims of gun violence by turning our tragedy into a moment of transformation. By empowering youth to ?know the signs? and uniting all people who value the protection of children, we can take meaningful actions in schools, homes, and communities to prevent gun violence and stop the tragic loss of life. The mission of Sandy Hook Promise is to end school shootings and create a culture change that prevents violence and other harmful acts that hurt children. Through our proven, evidence-informed Know the Signs programs and sensible, bipartisan school and gun safety legislation, we teach young people and adults to recognize, intervene, and get help for individuals who may be socially isolated and/or at risk of hurting themselves or others.
