As a property owner, you may wonder, “What is a certified arborist?” In short, an arborist is a professional with extensive training in expert tree care to protect your landscape and property overall. Read on as the leading provider of expert tree services in Newberg, Oregon, discusses what the profession is all about.
A certified arborist is a qualified tree care professional who has met strictly defined educational and testing standards in arboriculture, which is the science and practice of tree care.
The most widely recognized credential is from the International Society of Arboriculture (ISA), which ensures arborists are knowledgeable, ethical, and safety-conscious. An ISA-certified arborist must pass a rigorous exam and commit to ongoing education and a code of ethics. You can rely on ISA certification to know you’re hiring someone who takes tree health seriously.

Understanding the Arborist Certification Requirements
To earn ISA certification as an arborist, a tree professional must meet specific requirements. These include:
- A minimum of three years of hands-on experience in tree care or a relevant degree
- A comprehensive exam covering everything from soil science and pruning techniques to pest control and tree risk assessment
- Continuing education to stay up to date on the latest research, safety standards, and tree care methods
Certification is much more than a one-time test. It’s an ongoing, permanent commitment to excellence in arboriculture.
What Does a Certified Arborist Do?
What is a certified arborist? ISA-certified professionals provide personalized, science-based care. That includes the Oregon Arborist team serving Newberg and the surrounding Willamette Valley. Here’s how a certified arborist can help:
Tree Health Expertise
A certified arborist is a tree health expert trained to diagnose and treat all tree problems, from diseases and pests to soil deficiencies and environmental stress. Whether your tree is dropping leaves prematurely or showing signs of decay, your arborist knows what to look for and how to treat it effectively.
Tree Risk Assessment
Is that old oak near your home still structurally sound? A certified arborist can perform a detailed tree risk assessment to determine whether pruning, cabling, or removal is the safest option. An arborist’s inspection is especially important after storms or when planning landscape changes near mature trees.
Professional Tree Services
From strategic pruning and storm cleanup to safe tree removals and planting recommendations, certified arborists deliver professional tree services that protect your property and everything on it.
