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 circle members are our partners as we work to engage communities and advocate on critical environmental issues. Through membership, the Leadership Circles help to protect our collections, drive our research on today’s most pressing environmental issues, and support our innovative programming as we work to connect the story of our natural world to what people care about most.

In recognition of their exceptional investment, Leadership circle members have unique access to all the Academy has to offer, including opportunities to meet with Academy scientists and curators to learn firsthand about the Academy's remarkable collections and research. Leadership Circle members also receive exclusive invitations to receptions and field experiences, go on specially themed behind-the-scenes tours of the museum and our collections, and much more.
