why isa cert. arborist? this i have a problem with. what started off as the naa (national arborist assoc.) wich set standards high so when one completed the test you knew you were gettin a good tree man/woman. the isa is a cheapened,dues collection agency. wich lobbies politicians so only isa cert. arborists can work in certain areas. c`mon cert. tree climber, certified arborist, board cert. master arborist, utility specialist, etc.....I trained through local 1919 out of pittsburgh tree trimmers only union. to become a journeyman i had to apprentice for 5 yrs,2000 yes 2000 class room hours work all weather conditions travel to 3 out of 4 divisions and to become a j-man have 3 crewleaders test me & believe me it wasnt a pretty tree that was chosen i am recognized through the dept of labor both state(pa) & federal for tree trimming and line clearance. now, anyone can be an isa cert arborist. i know people who have never been in a tree who are isa cert arborists. the isa should be ashamed!! i hope you would consider other than isa arborists.by the way if you dont believe me go to isa web site punch in members list & check out the cert. arbs in pittsburgh area all those with the initials DQE(duquesne light co.) behind their name have never been in a tree. nice for our trade uhh???
