As one of Michigan's first certified arborists (since 1991), I have been working with trees for over 45 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 Michigan Certified Pesticide Applicator, a former Certified Nurseryman (MNLA - MCN 794), and a former Master Gardener.
