I have been in this corporate 8 years now and so have gained an insider's perspective on the tree care industry. In addition to our own booming little tree business I have been a climber meant for about 20 different companies. Some people say I was "on the bounce." I was kind of a mercenary tree guy. Most of my climbing know-how has been in Arizona, California and Hawaii. It has been a great way to travel! California and certainly Hawaii undoubtedly have some huge trees but Arizona has a few as adequately. So, in no particular order here are some thoughts on how to choose a tree company. Primary of all, let's clear up this Certified Arborist myth.
