Looking back on the past ten years of the Volunteer Ministers movement: 2001
Eight hundred Scientology Volunteer Ministers from the U.S. and abroad worked tirelessly for months in the toxic ruins of Ground Zero, New York, to support the massive rescue and cleanup effort. Along with international relief organizations such as the Red Cross and VOAD (Volunteer Organizations Active in Disaster), they organized the donation and distribution of food and other needed supplies to first responders and rescue workers. In addition to caring for their physical needs, they provided Scientology assists to relieve spiritual and emotional trauma.
