Lambert House began in the early 1980's as the Association of Gay and Lesbian Youth Advocates (AGLYA), a group of youth and youth supporters who came together in order to create ways for sexual minority youth to meet. On May 1, 1981 AGLYA became the first social service organization 100% dedicated to LGBTQ youth to receive 501(c)(3) status from the IRS.
In 1991 AGLYA seized an opportunity to lease an old Victorian house in Capitol Hill, Seattle's LGBTQ neighborhood. In 1993 AGLYA was renamed Lambert House after Gray Lambert, a local LGBTQ youth advocate who helped secure funding to find the organization a more stable home. Gray Lambert died of HIV/AIDS related complications in August of 1991.
Within two years the board hired the first paid staff members. Today, Lambert House has a national reputation as a leading organization in the Northwest for queer youth.
