Join the Director’s Circle at the Arnold Arboretum

Director's Circle Members

Be a part of a dynamic group of supporters who share the Arboretum’s values and vision for sustainable horticulture and landscapes, global change research, and educational opportunities.

The grandest of our leadership donor circles, the Director’s Circle represents the lifeblood of the Arboretum, providing the director with a vital source of ongoing, annual funding that is pledged over multiple years. Only the eighth director in the Arnold Arboretum’s 150-year history, William (Ned) Friedman offers a compelling vision for our next century that will require both investment and enhanced operational sustainability. Achieving his bold plans for the future will require the confidence, commitment, and support of a new circle of friends.

In addition to making the most significant investments in our landscape in more than a century, we are reaffirming our institutional commitments to equity in the landscape and addressing the pressing challenges of global change. Alongside these advancements, we aspire to strengthen the long-term sustainability of the Arnold Arboretum.

Our Director’s Circle will play an essential role in achieving our goals while building a broader base of unrestricted, multi-year operating support.

To acknowledge the generosity of our Director’s Circle members we offer unique programming—pop-up events in the landscape, salons, and an Autumn Dinner hosted in the Arboretum. Members will enjoy these fun and enriching opportunities while supporting an institution that has become increasingly important to Boston—not only as one of its most exquisite gardens, but as an important public health refuge and hub for global change research. We welcome any questions about our Director’s Circle and hope you will consider joining.
