Arboretum Staff

Content Detail

The Morton Arboretum’s vibrant staff includes 235 full-time, 135 part-time, and 120 temporary employees who work in areas such as plant collections and grounds, tree research, education, visitor services, and administration. Employees come from diverse backgrounds and share a common commitment to the mission of the Arboretum: to collect, study, display, and conserve trees and other plants from around the world to inspire learning, foster enjoyment, benefit communities, encourage action, and enhance the environment.

The vision of The Morton Arboretum is a greener, healthier, more beautiful world where people and trees thrive together. The management team leads the staff to achieve the goals of three interlinked strategic priorities: to engage local and regional communities, with attention to changing demographics and means of engagement; to conduct and share innovative research that advances tree science regionally and globally; and to conserve and promote resilient and adaptive trees and forests.
