Integrity delivers exactly what they promise - and then some. They're on time, they call if there is a delay (and they reschedule right away), they take time to determine what needs to be done and review with the customer before any promises/decisions are made. They've thinned a (very) mature Aleppo pine and African sumac for us; removed trees and remaining stumps; and thinned and treated two palo verdes for borer grubs. (when a flying piece of trunk shattered a very large window, they called and a replacement was arranged almost before the glass was swept up). If you'd like a preview of their work, Integrity's owner (John Eisenhower) frequently offers classes on tree pruning and maintenance in conjunction with the Desert Botanical Garden - and the classes are well worth your while if you're a homeowner with trees!
