The Door's mission is to empower young people to reach their potential by providing comprehensive youth development services in a diverse and caring environment. The Door serves up to 11,000 youth annually across four New York City locations. Broome Street Academy, a charter high school embedded at The Door, enrolls up to 330 students and prioritizes applicants who are experiencing housing instability or have been involved in the child welfare system.

At The Door, young people between the ages of 12 and 24 can access comprehensive services—health care, education, mental health counseling and crisis intervention, legal assistance, high school equivalency and college preparation services, career development, housing support, arts, sports and recreational activities, and nutritious meals—all for free.
