Parry Center for Children, located in Portland, Ore., is operated by Trillium Family Services, one of Oregon's largest nonprofit providers of mental health services to children and their families. Trillium provides a full array of treatment services at its four campuses in the state. Its programs include psychiatric residential treatment, outpatient services, community-based and school-based services, in-home services, therapeutic foster care, child mentoring services, and day treatment and therapeutic school services. Trillium was formed in 1998 when three agencies, the Children's Farm Home in Corvallis, the Parry Center for Children and Waverly Children's Home in Portland, merged to create an integrated care system with a statewide reach.
