Certified Trees is a Phoenix-based arborist company built on one principle: treat every tree like it matters. Because it does.
How We Started
Certified Trees was founded with a simple frustration: too many homeowners were watching their trees decline because they couldn't find someone who actually knew what was wrong. General landscapers would trim and spray without diagnosing. Trees would get worse, not better.
We built this company around proper arboricultural science. That means soil testing, root-zone analysis, and targeted treatments — not guesswork. It means being honest when a tree can be saved and equally honest when it can't.
Today we serve the entire Phoenix metro area, specializing in the sick and struggling trees that other companies give up on. Palms, desert trees, ornamentals — if it's in the ground, we can help.
Most tree companies focus on trimming and removal. We focus on keeping trees alive. Our deep-root soil aeration and targeted fertilization programs have saved hundreds of trees that homeowners thought were beyond help.
Credentials & Training
Certified by the International Society of Arboriculture — the gold standard in professional tree care.
Arizona licensed contractor with full liability and workers' compensation coverage on every job.
Specialized training in diagnosing and treating tree disease, nutrient deficiencies, and palm health.
Advanced soil aeration and root-zone fertilization techniques that most companies don't offer.
How We Work
We don't guess. Every job starts with a proper assessment — understanding what's actually wrong before recommending any treatment.
If a tree can be saved, we'll tell you how. If removal is the only safe option, we'll tell you that too — no upselling, no unnecessary work.
We leave your property cleaner than we found it. Debris hauled, stump ground, site swept. Done right the first time.
Our goal isn't just to fix the immediate problem — it's to set your trees up for decades of healthy growth.
