One year ago, twenty first-graders and six educators lost their lives in the tragic Sandy Hook Elementary school shooting. And every year, more than 30,000 lives are cut short by gun violence.

After losing her daughter Ana Grace, Nelba Marquez-Greene has spent the last year working for change with community members and other families who lost loved ones in the shooting. Sandy Hook Promise is committed to turning their tragedy into transformation from the community up - so that no other families have to feel their pain.
