Leadership Circles of Giving

opening the door to the Academy

Leadership gifts play a critical role in sustaining the Academy's scientific research programs, which explore today's most significant questions in environmental science, biodiversity, and evolution.

Leadership donors also ensure the conservation of the Academy's priceless collections of more than 18 million specimens—including such treasures as John James Audubon's birds and Thomas Jefferson's fossil collection—and sustain the Academy's programs of education, exhibits, and public discourse around the most important environmental topics of our time.

In recognition of their exceptional generosity, Leadership donors have special access to all the Academy has to offer, including opportunities to meet with Academy scientists and curators to learn firsthand about the Academy's outstanding collections and research, exclusive invitations to special receptions and exhibit previews, behind-the-scenes tours, and much more.
