Ohio Chapter ISA
Thank you for your interest in the Ohio Chapter of the International Society of Arboriculture (OCISA). We are a group of people who are passionate about trees and making the planet a better place. We are ground workers, climbers, equipment operators, researchers, industry suppliers, teachers, trainers, students, owners, managers, and all-around great people.
The Ohio Chapter is the successor of the Ohio Chapter of the National Shade Tree Conference organized in 1942 and then the Ohio Chapter of the International Shade Tree Conference in 1961. In 1975, the Chapter became the Ohio Chapter International Society of Arboriculture. The Chapter is established in the state of Ohio as a 501(c)3 charitable organization. In early 2026, the Chapter's Board of Directors redefined the Chapters mission and vision statements:
Mission Statement ~ To advance the practice of responsible tree care while promoting the benefits of trees through education.
Vision Statement ~ Connecting people through trees and urban forests.
