Spencer was impressive from the get-go. (The mystical answer to how he knew we had three dying, 60-foot tall Scots pines in our back yard remains in the cosmos.) Weeks before we met, he (or someone) had left his over-sized business card dangling from our front door knob.
Details: I called him one morning; he gave me a cost quote at lunchtime that day; we got more quotes, all in the same range (I'm in the wrong business!), but Spencer's follow-up sold us on him. He and his two-man crew arrived three days later.
Spencer scaled the first tree (how could anybody be that comfortable with a chain saw sixty feet up?), had it down to the ground and systematically ready for the chipper in about an hour, and they were all having fun as the remnants were hauled through our gate to the driveway. Our tight working area (the property-line fence, rock garden, smaller trees, shrubs, and flowers) posed challenges, but those "obstacles" didn't hinder their performance even slightly. They respected our environment, left the property damage-free, and clean-up was thorough, right to the street. We were very happy with the results, need I say, and would recommend Spencer (and his crew) without reservation.

I had an ash tree in my yard that was dying due to ash borers and required removal before any damage to my home of property occurred. I had Spencer of Alpine Arborist come to perform the removal. He removed all limbs utilizing a chipper, cut and stacked all of the larger pieces for me since I have a fireplace and left the property neat and clean! See photo of finished wood pile!
