Featured, recognized and heard across

A.T. Mitchell-Mann was born and raised in Brooklyn. In 2004, after eight-year-old Daesean Hill was killed by gunfire, he helped transform grief and outrage into Man Up! Inc.—a community organization committed to interrupting violence and creating real alternatives for young people and families.
Man Up! adopted the Cure Violence public-health model in 2009, pairing credible messengers and conflict mediation with education, employment, mentoring, fatherhood engagement, arts, sports, and emergency support.
That ground-level experience positioned A.T. to shape citywide strategy—not as an outsider studying communities, but as a practitioner accountable to them.
