Sean O’Connor joined Audubon as Chief Development Officer in 2017. Under his leadership, Development has evolved into a more sophisticated philanthropic partner. Participation in giving by volunteers and friends, including national and state boards, has increased since he took the helm, and overall donor investmenthas grown by an average of $7.5 million annually (26 percent).

Sean and his team launched Elevate, the most ambitious fundraising campaign in Audubon’s history, to advance bird-friendly policies, protect the places birds need, and engage people in support of Audubon’s mission. As of year-end 2021, Elevate had raised $650 million, providing transformational investments in vital climate change policies and solutions, hemispheric conservation initiatives, and greater equity and inclusion at Audubon and throughout the environmental movement.

He has also worked with The Nature Conservancy, Make-A-Wish Foundation, Boston Children’s Hospital Trust, and many other organizations.
