What Is A Certified Arborist?

Certified Arborist

Certified Arborists are individuals who specialize in the art and science of tree care. They are often referred to as the expert “tree doctors” of the environmental world, as they are trained to abide by guidelines established by the International Society of Arboriculture (ISA).

In order for them to work for a licensed and insured tree service company, Certified Arborists are required to go through years of training and take an extensive exam. They commit to the ISA Code of Ethics and honor it each day they come out to your property.


Certified Arborists:

  • Assess the health of your trees and decide if a tree should be removed.
  • Determine if pruning is necessary and, if so, what type of pruning should be used.
  • Identify insects & diseases as well as provide solutions to protect the tree or shrub from them.
  • Recommend types of trees appropriate for specific locations (ie: best tree planting practices).
  • Provide expertise to make sure there is no property or environmental damage.
  • Provide creative solutions to your needs.

Certified Arborist 1Why Should I Hire A Certified Arborist?

The typical run-of-the-mill tree guy hasn’t taken time to fully understand the various aspects of arboriculture. “Tree guys” tend to be untrained workers who are not licensed, don’t belong to an insured company, and lack the proper tree knowledge needed to care for trees and shrubs. This leads to tree damage, property damage, and liability if injury occurs.

Tree Damage:

Improper practices leads to insect infestations, decay, diseases, and sometimes the death of your tree. You could end up spending hundreds to thousands of dollars to treat your trees to mitigate the damage caused by improper care.

Property Damage:

When removing thousand pound trees or large branches, it is easy to cause property damage if you don’t know what you are doing. Untrained “tree guys” will not have the right equipment or training to make sure your property is safe while performing your contracted tree work. On top of that, unprofessional companies routinely refuse to repair or fix the damages they caused.

Liability For Injury:

Arboriculture is among the top five most dangerous occupations in the U.S, and that is regarding people that are professionally trained and have the right equipment. It gets even more dangerous when it’s performed by “tree guys” that are untrained and do not have proper safety equipment.

To add to this, most unprofessional companies are also uninsured or underinsured. This means if a worker from an uninsured or underinsured tree company hurts themselves or dies on your property, you can be held liable for their medical bills and may face multiple lawsuits.

Instead, choose a TCIA Accredited Company That Employs Local Certified Arborists:

When you chose a Local Certified Arborist you get a well trained professional that cares about you, your tree and your property.  These Certified Arborists will have the education and hands-on skills to properly evaluate your tree and provide a solution. And if something does go wrong a professional, licensed, & fully insured company will cover the costs to fix it.

    I recently bought a house on a lot with several poplar and oak trees. I’d like to get an analysis on the health of these trees; potential dangers to the house; and whether or not they have commercial value if felled.

    When is the best time of year to call a certified arborist to render an opinion on these matters?


    1. Rtectree says:

      Mr. Sholander,

      Thank you for your interest and question.

      Winter is a great time to get you trees evaluated and felled/pruned by a certified Arborist. Without leaves on the trees the Arborists are able to see structural weaknesses that may have been hidden by foliage during spring and summer. Winter is also the best time to prune most species of trees.

      We would be more than happy to send an Arborist out to evaluate your property. I will reach out to you via email to continue this discussion and possibly set up an Arborist consultation.

      Have a wonderful day,
