Cousins Tree and Shrub Specialists have been handling trimming and treatment services for us for several seasons now, and we couldn't ask for more orofessionalism. These folks are arborists, and not tree butchers. They know their trees and shrubs, and what's best for them. We have a glorious ash tree in our backyard, and Cousins have been treating it against attack by the ash borer insect, and the tree remains perfectly healthy. I would not even think about having anyone else to do this work.
