The center allows for more foster parents to afford to care for state children, while also allowing the children to acquire their own clothes, toys, and be much like any other child after losing everything when pulled from their biological homes. The organization's donation/distribution center, located at 115 Mansell Place in Roswell GA is set up like a retail store and is fully stocked with clothing, toys, bikes, highchairs, and other necessities, where foster parents throughout the state can come, by appointment, and shop for free.
