A Certified Arborist is not the same as a tree service or tree trimmer. When you hire a Certified Arborist, you know you’re getting the best possible tree care for your property and landscape. Certified Arborists must meet strict standards, including passing a rigorous exam, and participate in ongoing continuing education in order to stay up-to-date on the latest science in tree health care and insect and disease management. In other words, arborists are the tree doctors in tree care.
