Parry Center for Children was the Portland campus name used by Trillium Family Services for psychiatric residential and inpatient services for children and adolescents. Trillium's current materials describe the former Parry Center as part of its Portland campus, with residential treatment for youth requiring 24-hour support for emotional and behavioral challenges (Trillium psychiatric residential).

Oregon licensing records identify Trillium Family Services as the licensee and describe the Parry Center for Children as serving children and adolescents, typically ages 5-17, who need 24-hour residential treatment for mental health challenges. The 2021 site-visit report described a locked facility, fenced and open recreation areas, therapeutic activities, crisis support, and 24-hour supervision by trained staff (Oregon DHS licensing report).

Trillium traces the modern organization to the 1998 merger of Pacific Northwest Children's Services and the Parry Center for Children. Its history page states that, in 2025, the organization unified its campuses under the Trillium Family Services brand, replacing the former "Parry Center for Children" name with "Trillium Family Services Portland Campus" (Trillium history).

Trillium separately describes secure inpatient treatment for children ages 5-14 in Portland and ages 14-17 in Corvallis, with referrals through Oregon's Health Services Division. The residential and secure inpatient descriptions show the Parry Center name as part of a larger continuum of child and adolescent mental health services rather than a standalone private boarding school (Trillium secure inpatient).
