Central Arizona Shelter Services (CASS) was formed in 1984 in response to the need for an agency to operate an emergency shelter for the homeless in Central Arizona. It is the largest shelter and service center for homeless people in Arizona, serving men, women and families with children.
CASS currently serves over 400 homeless individuals downtown and 34 families with children at Vista Colina, a family shelter in North Phoenix. CASS serves up to 1,000 individuals each night and provides clients with hygiene supplies, shower and laundry facilities, and emergency clothing.
