We read the tree, not just the quote.
Certified arborists who read a tree from the canopy to the roots.
Heartwood was founded in 2008 by Cole Hargrove, an ISA Certified Arborist who got tired of watching crews top healthy trees for a quick fee. Seventeen years on, we are a team of certified arborists and trained climbers serving the Portland metro the way the canopy asks to be read — from the leaf to the root collar. We rig and lower, we use cranes when the cut calls for it, and we leave a tree healthier than we found it or we tell you honestly that it has to come down.
Certified, named, up in the tree.
