 In April of 1997, the city officially launched its first formal volunteer program- Volunteer Thornton- to oversee ongoing volunteer operations. Volunteer Thornton is a progressive program created to managed volunteers who assist in implementing programs and services in various city departments. Today, Thornton is distinguished by the spirit of its citizens who are actively involved in promoting the welfare of the community. This spirit of involvement is at the very foundation of our community. This traidtion of responsibility has been passed on and is a driving force for shaping the city of Thornton's future. Volunteers are essential to preserving Thornton's quality of life and making it a more rewarding and nurturing place to live and work.
