International Society of Arboriculture

50% of the Tree Geek staff is International Society of Arboriculture (ISA) certified (wahoo). This credential identifies professional arborists who have hugged trees and worked in the tree care industry for at least 3 years, and who have also passed a super duper examination covering all aspects of arboriculture.

Although it’s not an ISA requirement, our Tree Geeks love trees so much it hurts. Seriously.
