ISA Certified Arborist Tree Consultations in Portland, Oregon

Certified Tree Answers Before Costly Decisions

Most tree problems are not what they look like from the ground. What appears to be normal leaf drop could be an early sign of Phytophthora root rot. What looks like a dead branch might be a symptom of Armillaria spreading through the root collar. Getting the right answer about what is happening with your trees requires someone with the training to look past the obvious — and that is exactly what an ISA certified arborist consultation delivers. All About Trees LLC offers professional arborist consultations across Oregon for homeowners who want answers, not guesswork.

Consultations are available throughout Portland, Oregon and the greater Portland Metro area, including Beaverton, Lake Oswego, Tigard, West Linn, Hillsboro, and Gresham. Portland, Oregon's climate creates specific tree health pressures — persistent soil moisture, root compaction from heavy clay soils, and late-season canopy diseases that are easy to misread. Our arborists work in these conditions daily and know what to look for in this specific region.

Our team brings 25+ years of arboricultural experience and holds ISA certification — the industry's most recognized credential for professional tree care. We are licensed, bonded, and insured, and Daniel participates directly in every consultation to ensure the assessment is thorough and the recommendations are realistic. Schedule your consultation through our contact page and we will come to your property for a full, in-person evaluation.

Services Covered Under Arborist Consultations

Tree Health Assessment

A thorough health assessment evaluates crown density, foliage color, bark condition, root collar health, and structural soundness. We document what we find, identify the likely cause of any decline, and give you a realistic picture of the tree's condition and long-term prospects.

Hazard Tree Evaluation

Some trees look fine from a distance but carry hidden structural defects that make them genuinely dangerous. We assess lean, decay, root damage, branch attachment angles, and soil stability to determine actual failure risk and recommend appropriate action before a failure occurs.

Pre-Purchase Tree Inspection

Buying a property with large trees means inheriting whatever condition those trees are actually in. We inspect trees prior to purchase and give buyers a clear report on health, structural concerns, and estimated maintenance requirements so there are no expensive surprises after the keys change hands.

Tree Preservation Planning

Construction projects near trees put root systems under severe stress. We develop preservation plans that establish protection zones, specify soil management requirements, and advise on construction sequencing to keep valuable trees alive through projects that would otherwise kill them silently.

Pest and Disease Diagnosis

Identifying what is affecting a tree requires knowing which pests and diseases are active in the Portland region, how they present at each stage, and what the realistic treatment options are. We provide accurate diagnoses backed by ISA training and direct experience with local disease pressure.

Written Arborist Report

For insurance claims, permit applications, legal disputes, or property sales, a written arborist report from a certified professional carries documented authority. We produce formal reports that meet the standards required by municipal arborists, insurance adjusters, and legal proceedings.
