The primary facility for Wheaton athletics since the 1990-91 school year houses Balfour Natatorium, Beard Field House, Emerson Gymnasium and the majority of the athletic department staff's offices. Also located within Haas Athletic Center are an athletic treatment center, equipment room, locker rooms, meeting spaces and the sports information department. The Tokarz Team Room, which was named for long-time custodial employee Joe Tokarz, is also situated in Haas Athletic Center.
Haas Athletic Center was named for Evelyn Danzig Haas '39, a college trustee from 1977 to 1989 and a former member of the Annual Fund Special Gifts Committee and the San Francisco Wheaton Club. Mrs. Haas was also a trustee or director of many charitable organizations, such as the San Francisco Museum of Modern Art, the San Francisco Children's Hospital, and the Council of the National Gallery in Washington, D.C. Prior to the complex's construction, Clark Recreation Center served as Wheaton's central athletic complex.
