ISA Certified Arborist Long Island
Expert tree health assessments, disease diagnosis, and risk evaluations by ISA-certified arborist Jim Caruso (#NE-7234). Honest advice — not just a sales pitch.
A second opinion you can actually trust
Most homeowners call a tree company when they notice something wrong — and get a removal quote. An ISA-certified arborist gives you a different answer: what's actually going on with your trees, and what your real options are.
Jim Caruso (ISA #NE-7234) has been diagnosing, treating, and advising on Long Island trees since 2009. He'll walk your property, assess every tree, and tell you what needs work, what can wait, and what's worth saving.
Tree health assessment
Full evaluation of your trees' structural integrity, canopy health, root zone, and bark condition. We flag what's concerning and explain why.
Disease & pest diagnosis
Long Island trees face specific threats: emerald ash borer, oak wilt, Dutch elm disease, and more. We identify and recommend treatment before it's too late.
Hazard tree evaluation
We assess whether a leaning, cracked, or declining tree poses a risk to structures. Written risk reports available for insurance and HOA purposes.
Soil & root zone analysis
Compacted soil, grade changes, and root damage cause more tree decline than disease. We diagnose underground problems before they kill the canopy above.
Post-storm assessment
After a major storm, a qualified arborist should evaluate every tree on your property — not just the ones that obviously fell. Hidden damage is the biggest risk.
Written arborist reports
Formal reports for property sales, permits, insurance claims, HOA disputes, or neighbor conflicts. Signed by our ISA-certified arborist. Recognized by municipalities across Nassau & Suffolk.

Frequently asked questions
What does an ISA-certified arborist do?+
An ISA-certified arborist is trained and tested in tree biology, diagnosis, pruning, and risk assessment. They evaluate tree health, identify diseases and pests, recommend treatment, and advise on pruning, removal, or preservation. ISA certification is the gold standard in the tree care industry.
When should I call an arborist instead of just a tree service?+
Call an arborist when you're unsure whether a tree is safe, sick, or dying — or when you want professional advice before making a removal decision. An arborist can often save a tree that looks bad but is actually treatable, and can identify hazards in trees that appear healthy.
Do you provide written arborist reports?+
Yes. For property sales, insurance claims, HOA disputes, or permit applications, we provide written arborist reports with observations, findings, and recommendations. These are signed by our ISA-certified arborist and typically accepted by municipalities and insurers.
Can an arborist save a tree that's been declining?+
Often yes. Declining trees are frequently salvageable with the right diagnosis. Common recoverable conditions include certain fungal infections, soil compaction, improper prior pruning, pest damage, and root zone issues. We'll give you an honest assessment — if the tree isn't worth saving, we'll tell you that too.
