Rhode Island Zoological Society (RIZS) is a registered 501(c)3 non-profit organization that supports and maintains Roger Williams Park Zoo. RIZS works to secure the public and private sector support needed by the Zoo to continue to develop new world-class exhibits, make significant contributions to conservation, and serve the community as a valuable source of environmental education, recreation, and economic development.
By the mid 1960's, like so many zoos across the country, Roger Williams Park Zoo was showing visible signs of neglect. One determined individual, Sophie Danforth, recognized that the Zoo was an extremely valuable institution in need of organized assistance. She founded The Society in 1962 to increase public awareness and support for the Zoo, and to raise funds from the private sector. All trustees are fully independent, voting members of the Board. They serve the Society’s mission with no remuneration.
