My name's Mike I'm from Johnstown PA im looking to start a tree service in Pittsburgh I've got experience running saws and falling timber of all sizes but I know this whole climbing thing is going to be new to me so I'd like to have some pointers and tips from some experienced arborists of what I need from square #1 to start a tree company in the future.
