An arborist is a specialist in the care of individual trees. Arborists are exceptionally knowledgeable about the need and care of trees and are trained and equipped. Hiring an arborist is a choice that should not be taken lightly. Proper tree care is an investment that can lead to substantial returns. Pruning or removing trees, especially large trees, can be dangerous work. Poorly maintained trees can be a significant liability. Well-cared-for trees are attractive and can add considerable value to your property. Tree work should be done only by those trained and equipped to work safely in trees.
