Jill Koski became the president and CEO of Holden Forests & Gardens on Nov. 28, 2017, assuming leadership of the organization that includes the Holden Arboretum in Kirtland, Ohio and the Cleveland Botanical Garden in Cleveland’s University Circle district.
Koski led the organization through a period of growth for the organization, with the Arboretum and Botanical Garden experiencing all-time highs in combined annual attendance (nearly 380,000) and membership (more than 17,000 households). The organization is also having a greater impact in the community, as evidenced by its integral role in the development and implementation of the Cleveland Tree Plan, the collaborative effort to increase the tree canopy coverage in Cleveland.
Before accepting the role as Holden’s president and CEO, Koski served as the vice president of development for the Morton Arboretum in Lisle, Illinois. Before Morton, she spent 10 years with Shedd Aquarium in Chicago, Illinois, in a series of progressively responsible development positions. Koski received her bachelor’s degree in political science from the University of Wisconsin-Madison. She is married with two children.
