About Us

The Zoological Society of Milwaukee

Mission Statement

The mission of the Zoological Society of Milwaukee is to take part in conserving wildlife and endangered species, to educate people about the importance of wildlife and the environment, and to support the Milwaukee County Zoo.

What is the Zoological Society of Milwaukee?

The Zoological Society of Milwaukee was established in 1910 as an informal group of community leaders who bought animals and raised funds for the Zoo. Today it is a non-profit 501(c)3 organization with the mission to conserve, educate and support the Milwaukee County Zoo. The Society has 50 full-time and 45 part-time employees who manage daily operations and programs. In the 2018-19 fiscal year, the Society raised more than $10.2 million to support the Milwaukee County Zoo.

A Rich History

In 2010, the Zoological Society celebrated its centennial anniversary. Since 1910, the Zoological Society has been a driving force behind Milwaukee’s Zoo, from the time it was the 38-acre Washington Park Zoo on Vliet Street in Milwaukee, Wis., through the move to its 209-acre location on Bluemound Road in the 1950s and today.

Supporting the Zoo

Helping the Milwaukee County Zoo maintain its reputation as Wisconsin's premier educational and cultural treasure is a big part of the Zoological Society's mission. Together, the Zoo and Society serve more than 1.3 million Zoo visitors a year. The Society and Zoo work together to attract both a strong family base as well as a diverse audience through free days, targeted school programs, evening concerts, special events and other efforts. Thanks to the vision of community leaders and the generosity of many friends, the Society has invested millions in capital improvements to the Zoo. The Society's support, through two capital campaigns, combined with matching dollars from Milwaukee County, has helped build animal homes that resemble natural habitats. These habitats include the Stearns Family Apes of Africa Pavilion, Primates of the World, the Herb & Nada Mahler Family Aviary, the Florence Mila Borchert Big Cat Country and the MillerCoors Giraffe Experience.

"Zoo support" also means raising funds to cover the cost of maintaining and creating educational and innovative exhibits, designing signs and graphics at the Zoo, creating brochures and other promotional materials, and funding several of the Zoo's wildlife research and conservation projects.

Zoo Pride Volunteers

The Society is fortunate to have a dedicated group of volunteers who are essential to our success in fulfilling the mission. Zoo Pride volunteers lead tours, assist with education programs, staff our information booths at the Zoo, help with special events, and provide clerical and staff support.

Zoo Pride volunteers donate more than 52,000 hours to the Society and the Zoo annually. Zoo Pride celebrated its 40th anniversary in 2015. Meet some of our volunteers here.

Zoological Society Education Programs

Throughout the year, the Zoological Society brings exceptional animal, environmental and science-based educational opportunities to children, adults and families. These programs are held in the Karen Peck Katz Conservation Education Center, the Society’s eight-classroom building on Zoo grounds. The programs help people of all ages develop an understanding of wildlife and some of the environmental challenges the earth faces.

For school classes, the Society's Conservation Education Department provides special programs in the Conservation Education building; Zoo to You classes brought by Society educators directly to schools, often with live animals; and self-guided Zoo tour materials that enhance teacher curriculum. Along with sharpening students' sensory and observation skills, animal programs and related materials help fulfill science standards set by the state of Wisconsin. Year-round classes and summer camps available to individual children and families offer hands-on learning activities focusing on the wonderful world of animals. Overall, these programs reach more than 300,000 individuals annually. The Society reached thousands more people with educational messages about animals and conservation through the Society website and email news to members, Society publications, Society-designed signage at the Zoo, Zoological Society programs in Africa, stories in the media about Society projects, and social media platforms such as Facebook, Instagram, Twitter, and Snapchat.

Conservation Programs

In the last quarter-century, the Zoological Society has made lasting contributions to conservation around the world and at the Zoo. Several animals that are in immediate danger of extinction have a better chance for survival thanks to the work and funding of the Society. The Society provides annual funds to the Milwaukee County Zoo to help support conservation and research projects, some of which involve Zoo staff. These projects have helped animals around the world, including orangutans, Humboldt penguins, giraffes and Grand Cayman blue iguanas.

Funding the Mission

Zoological Society Membership

Annually, the Society brings in more than $6 million in Zoo Pass memberships. The Milwaukee County Zoo receives 50% of all Zoo Pass memberships in direct cash support. Members of the Society receive many benefits, including free admission to the Milwaukee County Zoo and more than 150 other zoos and aquariums nationwide. Members also receive a subscription to Alive, the Society's exclusive member magazine; Wild Things, the Society's event newsletter; discounts on education workshops and Zoo gift-shop purchases; and invitations to special members-only events and programs. We are fortunate to have a loyal group of members.

Serengeti Circle

The Serengeti Circle, a Society sponsor- and grantor-recognition program established in 1994, is a valued group of corporations and foundations that supports the Zoo and Zoological Society through grants and sponsorship of special events, traveling exhibits, attractions and education/conservation programs at the $2,500 level and above. Sponsors and grantors are recognized at the Zoo and in the Society's annual report and are invited to attend new Zoo exhibit premieres and a fall recognition dinner.

Platypus Circle

The major donors of the Zoological Society are recognized through membership in the Platypus Circle. Members include more than 400 area foundations, businesses and individuals contributing more than $716,000 annually with in-kind services and support. Platypus Circle members receive exclusive benefits, including VIP admission cards to the Zoo, invitations to previews of new exhibits, behind-the-scenes tours and an autumn awards dinner.

Animal Sponsorship Program

From $25 to $2,500, the animal sponsorship money helps the Zoological Society fulfill its mission. Children can sponsor animals through our Kids Conservation Club, through school classes or as individuals. Adults who love animals can sponsor their favorites. All of our sponsors are invited to a behind-the-scenes event at the Zoo in August and receive information about their sponsored animal.


The Zoological Society established its grants program in 1989 with a budget of $42,000. Last fiscal year, we raised $1.27 million in grants, which support education programs at the Zoo or offsite as well as numerous conservation programs.

Fundraising events

Each year the Society hosts events that raise money, entertain guests, and build community support—all at the same time. Zoo Ball is the Society's biggest fundraising event. Held annually since 1984, the event raises funds to help support Zoo building projects, conservation projects and education programs. The Birdies and Eagles Golf Tournament, Zootastic and Ride on the Wild Side family biking event also have become popular Society fundraisers. Funds raised from these events go directly to Zoo exhibit renovations, education programs and conservation projects. The Society’s special events raise almost $1 million annually.


The Zoological Society draws upon the special generosity of its members, donors and special event-goers for important unrestricted annual operating support. Besides supporting the Zoological Society through annual dues, members also have a chance to contribute to the Society's Annual Appeal. Proceeds from the appeal typically go toward a specific project to benefit the animals. We also look with increasing urgency to other areas of supplemental income: private and corporate foundation grants, endowments, and promotional partnerships with area businesses, memorial and honoree gifts, corporate sponsorships and in-kind donations. Combined, these vital sources of support will help the Society face the future challenges of strengthening our education outreach, conservation and Zoo support programs.
