Giving Circles
Yerkes Future Foundation Giving Circle Program Levels and Benefits 2023-2024
Yerkes Future Foundation Giving Circles program recognizes donors who support our work with an annual, repeating unrestricted gift of $300 or more.
Each Giving Circle is named after an individual who played an important role in our story: architect Henry Ives Cobb, landscape architect John Charles Olmsted, and astronomers Mary Calvert and Nancy Grace Roman. The George Ellery Hale Patrons are named after the founder of Yerkes Observatory.
Your generosity ensures that the work of these visionaries from our past endures for present and future generations of visitors, students, and families to experience.
Join one of our Giving Circles using the donation form below. Thank you!
