William G. Steiner (born April 26, 1937, Sibley, Iowa) is a children's advocate and nationally recognized expert on child abuse and neglect, a former chairman of the Orange County, California board of supervisors, founder of both the Orangewood Children's Home, located in Orange, California and the Good Samaritan Boy's Home, in Corona, California, and a former school board member and city councilman for the City of Orange. In addition to his numerous positions as a public official and child advocate in the non-profit sector, he served 16 years on the board of directors for the National Center for Missing and Exploited Children, based in Alexandria, Virginia.
Steiner earned his bachelor's degree in criminology from the University of California, Berkeley, and his master's degree in social work from the University of Southern California.
While still in his twenties, Steiner founded and became the director of the Good Samaritan Boy's home, which expanded over the years to include a number of group homes across California.
In 1985, the Orangewood Children's Home, a public-private partnership, opened its doors to serve as Orange County's transitional shelter for children, after Steiner led efforts to raise $8.5 million for the facility. Steiner served as executive director of the Orangewood Foundation, which over the years has raised over $20 million to address problems of child abuse and neglect in Orange County.
California Governor George Deukmejian appointed Steiner to the State Child Development Programs Advisory Committee in 1986, and from 1990 to 1998 he served as a policy advisor to the Cabinet Secretary for Child Development and Education in the Administration of Governor Pete Wilson. He has taught Political Science at the University of California, Irvine, Public Policy at the University of Southern California, and child abuse courses at Chapman University. Steiner has also worked with the California Youth Authority, the Los Angeles Department of Adoptions, Metropolitan State Hospital, and various residential treatment agencies serving abused and neglected children.
