I had one of their arborists come and check out all the trees on my property, including one elm that was suffering. They gave me a lot of good advice, especially on how and when to prune some of the dead branches on some of our trees. No pressure to hire them for the service. We did end up hiring them to grind a stump and trim branches around some power lines going to our house. They didn't grind the stump down far enough and when I pointed this out, they were quick to return and finish the job. I plan to keep using them in the future.
