re: Long shot, but is anybody on here a certified arborist?

My uncle is an Arborist on the Wank. He came to visit us in Alabama and my mom had hired some door to doors that were going around the neighborhood. My uncle noticed that they were climbing live trees with spikes to trim them.
So he went and asked them if they were licensed Arborists.
They answered "No sir, we're brothers and we're Mitchel's"
He went back inside....
