What is an ISA Certified Arborist?
An ISA Certified Arborist is a tree care professional who has demonstrated extensive knowledge in:
-
Tree biology & structure
-
Tree health, disease, and insect diagnosis
-
Tree risk assessment procedures
-
Proper pruning techniques
-
Safe rigging and tree removal
-
ANSI Z133 safety standards
-
Soil health, nutrition, and environmental factors
-
Plant Health Care (PHC) and micro-injections
​
Certification requires ongoing education, meaning you always receive up-to-date, science-backed recommendations.
Why Hire an ISA Certified Arborist?
Accurate Diagnosis - We identify what’s actually affecting your tree—fungus, insects, stress, structural defects, or environmental conditions—so you’re not guessing or paying for unnecessary work.
​
Improved Safety - Tree risk assessments help prevent falling limbs, structural failures, and property damage. Certified arborists use established protocols to evaluate trees near homes, driveways, and high-traffic areas.
​
Proper Pruning & Care - Incorrect pruning can permanently damage a tree. We prune according to ANSI A300 standards, ensuring long-term health and aesthetics.
​
Ethical Recommendations - We never recommend removals unless they’re necessary. Our goal is to preserve healthy, safe trees whenever possible.
​
Insurance & Real Estate Documentation - We provide arborist letters, reports, and risk evaluations for homeowners, insurance adjusters, HOAs, and property managers.
