Why hire a Certified Arborist?

by the International Society of Arboriculture

An Arborist, by definition, is an individual trained in the art and science of planting, caring for, and maintaining individual trees. Arborists are knowledgeable about the needs of trees and are trained and equipped to provide proper tree care.

Hiring an arborist is a decision that should not be taken lightly!

Proper tree care is an investment that can lead to substantial returns. Well-cared-for trees are attractive and can add considerable value to your property. Poorly maintained trees can be a significant liability. Pruning or removing trees, especially large trees, can be dangerous work. Tree services should be completed only by those trained and equipped to work safely in trees.

Arborist Consultations and Reports

Consulting Arborists are the educated authorities on matters relating to trees, ensuring the safety, health, and preservation of trees in our natural surroundings. Both homeowners and industry professionals will find a number of different reasons to hire a Consulting Arborist to achieve their tree care objectives.

Trees in our developed environment present a challenge, requiring careful planning and vigilant maintenance. The shared public trust of governments, businesses, and homeowners is to ensure that trees grow, thrive, and remain safe. When a problem occurs—if a tree causes damage or becomes a public safety hazard – a source for advice and mediation is often needed. This is the role of the Consulting Arborist: to bring a comprehensive, objective viewpoint to the diagnosis, appraisal, and evaluation of arboricultural issues.

As a graduate of ASCA’s Consulting Arborist Program,  Scott Clifton, of Treewise, LLC, has been dedicated to the objective assessment of trees, total quality tree care services, the enhancement of the community, and the protection of the environment for many years.
