ISA Certification



ISA stands for the International Society of Arboriculture which sets the standard for tree care across the globe. One thing we like to stress is the importance of working with an ISA certified arborist for all of your tree care needs, but why?


Certification requires at least 3 years of tree care experience, education or a combination of the two. Once this is met a candidate is required to pass a comprehensive exam. Subjects covered in the exam include; Soil & Water ecology, Tree Biology, Diagnosis & Disorders, Risk Assessment & Tree Protection and, of course, Tree Worker Safety. In order to maintain certification, this exam must be retaken and passed every 3 years.


ISA is also an extremely active community. Being a part of it means you have access to newsletters and other publications that are constantly being updated with new tree care tools and techniques.
