An arborist is trained in all matters of tree health and safety. If you have a tree that’s newly damaged, overgrown, sickly, or poses a threat, then an arborist should conduct a site visit and determine the best course of action. An arborist may even decide that trimming a tree is the best choice for the tree’s health. Much like an arborist, a tree trimmer can help maintain the health of your trees and provide necessary tree care. If you would like a tree trimmed for aesthetic reasons, a tree trimmer is more than capable of doing the job.
