William Kellibrew has extensive experience in addressing sexual assault, violence, and trauma. He has worked with the Substance Abuse and Mental Health Service Administration’s (SAMHSA) National Center for Trauma-Informed Care and Alternatives to Seclusion and Restraint, SAMSHA’s Bringing Recovery Supports to Scale Technical Assistance Center Strategy (BRSS TACS), United States Department's Office for Victims of Crime Training and Technical Assistance Center, and the Office of Juvenile Justice and Delinquency Prevention’s National Training and Technical Assistance Center. His work has spanned addressing substance-use and the opioid epidemic, mental health challenges, domestic violence, sexual assault, children witnessing violence and homicide, among many other pressing societal challenges. William also has personal perspective.

At age 10, William witnessed the murders of his mother, Jacqueline and 12-year-old brother, Tony, in their living room on July 2, 1984, by his mom's ex-boyfriend. The killer took his own life that day, but not before making William beg for his life at gunpoint. William shares his personal and professional journey of healing and resiliency across the globe. William has emerged as a global advocate and authority on addressing violence and trauma throughout multiple systems and settings. His synergy with the audience is inspiring and motivating as he provides a practical approach to supporting individuals, families, and communities impacted by sexual assault, violence and trauma.

Among the many acknowledgements of William’s passion and service, in 2011, the White House recognized Mr. Kellibrew as a “Champion of Change,” and in 2013 SAMHSA awarded him the Voice Award for his work across the country as a peer/consumer leader. In 2014, he accepted the Capitol Probe Award at the District of Columbia Hall of Fame Induction Ceremony, and in 2015 he received the U.S. Congressional Victims' Rights Caucus Eva Murillo Unsung Hero Award. William credits his grandmother and others for supporting him on his life-long journey of healing.
