What Does a Certified Arborist Do?

A Certified Arborist is a tree care professional who has passed the International Society of Arboriculture (ISA) exam, adheres to ANSI A300 standards, and maintains ongoing education in tree biology, pruning, risk assessment, and safety. Our arborist services include formal tree risk assessments and emergency evaluations when trees pose immediate hazards.


Unlike general tree workers, certified arborists specialize in:

  • Tree health and disease diagnosis to identify pest activity, decline, structural defects, and environmental stress factors.
  • Structural and hazard evaluations using ISA Tree Risk Assessment (TRAQ) methodology and industry best practices.
  • Species-specific pruning standards based on ANSI A300 pruning guidelines and long-term tree health objectives.
  • Root issues, soil conditions, and site factor assessments for trees affected by excavation, grading, or construction activity.
  • Municipal tree codes and compliance guidance for protected trees, removal permits, and environmentally critical areas (ECAs).
  • Emergency tree assessments for storm damage, cracked stems, root plate movement, or immediate failure concerns.
  • Tree preservation planning around construction to reduce impacts to roots, canopies, and soil conditions.
  • Certified Arborist Reports for permits, insurance claims, neighbor disputes, and documented tree risk evaluations.

When you hire an arborist, you’re hiring a qualified expert who makes decisions based on science, safety, and correct industry practices—not guesswork.
