What we do

Full-canopy care, done by certified crews.

Six core services — from a single overgrown limb to a hazardous removal beside your roofline. Every job starts with a free arborist assessment.

Tree Removal

Safe, sectional take-downs of large or failing trees — rigged down piece by piece, never dropped on your house.

Removals quoted on-site Request a removal quote →

Trimming & Pruning

Structural pruning that keeps trees healthy, clears roofs and lines, and holds their natural shape.

Free estimates Book a pruning visit →

Stump Grinding

Old stumps ground below grade so you can replant, reseed, or reclaim the lawn — chips and all cleaned up.

From $95 per stump Grind a stump →

Emergency Storm Response

Limb through the roof or a tree down across the drive? Our 24/7 line dispatches a crew to make it safe fast.

24/7 storm line Call the storm line →

Tree Health & Disease Assessment

A certified arborist diagnoses decline, pests, and root issues — with a written plan to save the tree where we can.

Assessment from $145 Get an assessment →

Crown Reduction

Careful thinning and height reduction that eases wind load and weight without butchering the canopy.

How it works

Calm, certified, and cleaned up.

No pressure and no guesswork. Four steps from your first call to a spotless yard.

  1. Call or request a quote

    Reach a real arborist — not a call center. Same-day scheduling for most estimates across the foothills.

  2. Free arborist assessment

    We walk the property, read the tree, and flag anything hazardous — honestly, even if the answer is "leave it standing."

  3. Written plan & quote

    A clear, itemized price with scope, access, and cleanup spelled out. No surprises once the saws start.

  4. Careful removal + full cleanup

    Rigged down in sections, hauled off, raked, and blown clean. You'd never know we spent the day there — except for the light.

"A 90-foot eucalyptus was leaning over the house and I was terrified. Their crew took it down in sections like clockwork — you'd never have known it was there. Calm, professional, spotless."

★★★★★
"The arborist actually talked me out of removing an oak two other companies wanted gone — pruned it instead and it's thriving. Honest people who clearly love trees. That's rare."

★★★★★
"After the windstorm a limb came through our patio cover at 6am. We called the emergency line and a crew was on-site before lunch. Fair price, careful work, full cleanup. Lifesavers."
