    Hiring a Certified Arborist vs. Tree Trimmer

    Tree trimmers that are not certified may not consider how their actions or techniques can impact the tree. Becoming a tree trimmer does not require any specific certification. Not every tree trimmer is a Certified Arborist. Proper tree trimming is an art that takes into account the health of the tree while also maintaining the natural aesthetics and beauty of a tree.

    The ISA Certified Arborist credential helps consumers identify qualified, ethical, and highly trained tree services.


    To become an ISA Certified Arborist an individual must:

    • Have 3 years of full-time experience working in the field while implementing proper tree care techniques;
    • Gain a recommendation by an ISA Certified Arborist; and
    • Sit for an extensive certification exam.

    Once certified, they are required to engage in continuing education to maintain the credential.

    ISA Certified Arborists are tree care workers that follow a strict code of ethics that ensures the reliability and credibility of their work. A Certified Tulsa Arborist will always consider the health and needs of each individual tree.

    Tree Pruning

    Pruning is the process of removing certain limbs, branches, or stems from a tree. It is much more than the simple act of sawing off some limbs. A Certified Arborist will always follow American National Standards Institute (ANSI) A300 Pruning Standards and will make informed decisions about how much and where to trim or remove, as well as use the proper technique to do so to help ensure proper healing and health. Proper pruning can help improve a tree’s structure and health.

    Tree Removal

    There are numerous reasons why a tree may be removed and it is often done because the tree is dead and/or is a threat to people or property. Tree removal, particularly large tree removal, requires specific knowledge and equipment and is a highly technical task. A Certified Arborist will be able to remove a tree in a safe and efficient manner.

    Emergency Tree Care

    A tree emergency is a tree that has become immediately hazardous, usually as a result of a storm or weather. Downed trees can present even more of a risk and should be left to a tree care company with extensive experience in responding to storm damage. A Certified Arborist will also be able to asses whether a tree can be saved or if removal is required.
