Tree trimming is more than just cutting down branches. Just because he was
able to remove downed trees quickly (and cheaply), that doesn't mean he'll
do a good job properly triming a tree. Be careful. You want to be sure that
there is an arborist in the team that will work on your trees, otherwise
you're risking too much.
