The Oklahoma Zoological Society (OZS/ZOOfriends) is a 501 (c) 3 and was created in 1954 to support and promote the Zoo and its four purposes of education, conservation, zoological research and recreation. OZS does this through membership drives, annual fundraising, capital campaigns, marketing, special events and public relations.
With more than 27,000 member families, OZS works in partnership with the Zoo in raising funds for special programs, exhibits, education, animal welfare, conservation initiatives locally and worldwide and research projects. A volunteer board of directors serves as the governing body for OZS.
OZS hosts three annual fundraising events held on Zoo grounds, ZooBrew, Ostrich Egg Breakfast and Zoobilation. OZS also hosts several smaller events that benefit the Zoo's conservation initiatives. ZOOfriends members participate in the annual Capture the Wild Zoo Photo Contest each July where photos are used to help produce a colorful calendar distributed to members each winter.
