The Friends of Pueblo Grande Museum (formerly the The Pueblo Grande Museum Auxiliary) was incorporated in February 1981 to serve as an advisory group for the Museum. The purpose of the organization is to assist Pueblo Grande Museum and staff in dispersing educational materials; to provide lecturers and tour guides; to assist in the preparation of exhibits, library cataloging and management, collection management, curatorial and conservation techniques, records management and research; and to organize, publicize and promote activities, events and fund raising for the Pueblo Grande Museum and Archaeological Park.
The organization and its members may inform the Parks, Recreation and Library Board and the City Council of the city of Phoenix, Arizona on matters relating to Archaeology and the Pueblo Grande Museum Archaeological Park. The Friends also operate the Museum store. The store offers a variety of southwestern arts and crafts and an extensive book collection, providing a valuable resource to the community and a significant source of revenue for the Museum.
