The ISA Certification Credentials: The Right Certification for the Right Job

The International Society of Arboriculture has been working hard with their members to raise the standards of professional tree care. The decision to choose the right arborist is very important. Trees are a lifelong investment and you want to protect that investment. The decision was once a simple one. Choose an ISA Certified Arborist!

Now, the ISA has been listening to their credential holders and have responded by developing a career path in arboriculture through their certification programs. Not only does this benefit the professional, it will benefit you when hiring professional tree care.

The ISA Certification credential can be viewed as a pyramid with the largest group in the base. These credentials were developed based on the knowledge required to obtain each one.

Why Hire an Arborist?

An arborist is a specialist in the care of individual trees. Arborists are knowledgeable about the needs of trees and are trained and equipped to provide proper 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 work should be done only by those trained and equipped to work safely in trees.
