I had them come out and trim two of my trees last year, chose them because I wanted a certified arborist who would do the work correctly. Instead, I have two trees that were cut so poorly that they are very heavy on one side of the tree, not evened out. One tree is now toppling due to being so heavy on one side and threatening my house, which I'll have to have cut down. The other tree - the only branch they cut off was the balancing branch, so now it is extremely heavy on one side only, now I'm going to need to have someone else cut it back properly. Very disappointed. And they left my side gate open which let my dog out, and when I called them about it they didn't even call back with an apology.
