The Treeline Conservancy Announces Executive Director

The Board of Directors of the Treeline Conservancy has selected Ellen ‘Nan’ Plummer as its first Executive Director.

Plummer has filled several leadership and fundraising roles, including as Senior Development Officer with the Arkansas Children’s Hospital Foundation, as Executive Director of the Arkansas Arts Center, and most recently as President and CEO of LexArts in Lexington, Kentucky.

Plummer has roots in the Ann Arbor community, earning MA, MBA and PhD degrees from the University of Michigan and serving as Assistant Director for Programs at the UM Museum of Art and Executive Director of Artrain. She and her husband, James Willard Spencer, maintain an art and music space, 22 North, in nearby Ypsilanti. Spencer is an original member of the local bluegrass band the RFD Boys, still performing regularly at the Ark in Ann Arbor.

Norman Herbert, a member of the Treeline Conservancy Board of Directors and co-chair of the search committee, says, “Nan is a collaborative, energetic and strategy-driven leader of nonprofit organizations. She is excited to get started on this creative and beneficial project for a place she dearly loves. This is an important moment for the Treeline as we move from concept to plans to construction and bring to life the vision of an urban trail through the heart of Ann Arbor.”



The Treeline Conservancy exists to foster the creation of an urban trail that becomes an integral connector of people and places in Ann Arbor. The trail will bring access to Ann Arbor’s river and park system through the heart of downtown along the alignment of historic Allen Creek; provide safe passage and recreation from Stadium Boulevard to the Border-to-Border Trail; invite community gathering and engagement with natural and cultural features; and benefit current and future generations by providing positive economic impact, improved aesthetics, enriched community engagement, and improved stormwater quality.
