Why Choose an ISA-Certified Arborist?

At Cooney’s Tree Surgeons, our lead arborist is ISA-certified—ensuring your trees are cared for by a trained, knowledgeable professional committed to safety, science, and industry standards.

An ISA-Certified Arborist is a tree care professional who has been trained, tested, and accredited by the International Society of Arboriculture (ISA). This globally recognized certification ensures that your arborist has a deep understanding of tree biology, proper pruning techniques, safe removal practices, pest and disease identification, and industry-approved standards for long-term tree health.

At Cooney’s Tree Surgeons, Brent Cooney—our founder and lead arborist—has completed ISA training and maintains certification through continuing education. That means you’re hiring someone who not only knows how to care for trees—but how to do it safely, ethically, and with the long-term health of your property in mind.
