When you hire a tree company, most of the conversation is about the arborist — the person doing the assessment and making the call on what needs to happen. But what about the crew members actually in the tree, operating the saw, and making the cuts that determine whether a job goes right? That's where ISA Certified Tree Worker certification matters, and it's a credential that doesn't get nearly enough attention.
An ISA Certified Tree Worker has passed a written and practical skills exam that covers rigging, climbing, chainsaw operation, and safe work practices at height. It's not just a piece of paper — it reflects documented competency in the hands-on work that tree care actually requires. The ISA Certified Arborist credential covers assessment and management knowledge. The ISA Certified Tree Worker credential covers the physical execution of tree work safely and correctly. Both credentials are important, and having both on your crew is what separates a professional operation from one that's winging it.
At ArborSafe, we have both. Our crews include ISA Certified Arborists and ISA Certified Tree Workers, and that combination is part of how we've maintained our standard of work in the Treasure Valley since 1997. Every job gets the right expertise at every stage, from the initial assessment to the final cut and cleanup.
If you've ever wondered what to actually look for when evaluating a tree company, credentials are a good place to start. Visit arborsafetreeservice.com to learn more about our team and our approach. When you hired a tree company in the past, did you ask about the certifications of the crew doing the actual work in the tree?
