During its lifetime, the Duquesne Club has grown from a handful of founding members to today's enrollment of approximately 2,400 men and women. For much of its history, the Duquesne Club was considered a "business club," with its members wielding tremendous impact on the city, region, country, and even the world. While leaders of the business community continue to be the largest component, membership today is broader based and more diverse than years ago. In addition to enjoying traditional services, members join to use the Club's athletic facilities, dine prior to attending cultural events, attend Club sponsored social programs, and enroll in special interest societies that foster camaraderie.
Membership is by invitation from an existing member only. The Duquesne Club does not discriminate in its selection of members on the basis of race, color, gender, or religion.
