Accredited Landscaping Maintenance and Repair Portland, OR | Certified Arborist

At General Tree Service, we are the arborists that keep the trees of Portland, OR healthy and safe all year round.

To provide you with the highest quality of service, we have several employees who have earned the ISA Certified Arborist credential. In addition to having been trained and knowledgeable in all aspects of arboriculture, they must adhere to a stringent Code of Ethics that strengthens the credibility of the workforce in the tree industry.

In order to be eligible for the exam, they have met one or both of the following:

  • 3 or more years of full-time, eligible, practical work experience in arboriculture
  • Degree in the field of arboriculture, horticulture, landscape architecture, or forestry from a regionally accredited educational institute.

Ongoing education is a priority of all our employees as we strive to deliver the highest quality of tree, shrub, and plant health care throughout Portland, Salem, and SW Washington.

ISA Board Certified Master Arborist

This is the highest level of certification offered by the ISA and recognizes those arborists who have reached the pinnacle of their profession.

In addition to passing an extensive scenario-based exam, they must abide by a Code of Ethics to ensure their quality of work. Less than two percent of all ISA Certified Arborists currently hold this certification.

Tree Risk Assessment Qualification

Several General Tree Service arborists have a Tree Risk Assessment Qualification or TRAQ. Through education and training, arborists learn strategies that include a standardized and systematic process for identifying and assessing tree risk.

We also provide information to tree owners so they can make educated and informed decisions concerning the safety of their family and property while considering the tree’s health and longevity.

How to Know When It’s Time to Call

When it comes to the trees in your yard, you can never be too careful. It might seem like an easy task, but trees are heavy creatures that aren’t as easy to maneuver as you might think. That is why it is always highly encouraged to have a certified arborist from General Tree Service around.
