About me

As one of Michigan's first certified arborists (since 1991), I have been working with trees for almost 50 years. My father founded AAA Tree Service in 1947 which I owned and operated for nearly twenty years.

In 1996, I started Porterfield Tree Care Consulting Inc. I am also a former Michigan Certified Pesticide Applicator, a former Certified Nurseryman, a former Master Gardener, and a former member of The American Society of Consulting Arborists.
