What is ISA?

The International Society of Arboriculture (ISA) -- -- has served the tree care industry for over seventy years as an educational organization. ISA was founded in 1924 by a small group of forty individuals. Today there are nearly 14,000 members throughout North America, South America, Europe, Africa, Australia, and Asia.

ISA is an outlet for arborists around the globe to "share their experience and knowledge for the benefit of society." ISA, working alongside several other organizations, continues its hard work aimed at providing a better understanding of trees and tree care through the education of tree industry professionals.
