I have been involved urban forestry since discovering the field as a summer seasonal for the University of Michigan’s Forestry Department in 1991. After a brief stint at Hendricksen, the Care of Trees , I moved to the Village of Glen Ellyn - Forestry in late 1992, working  up to the crew leader/supervisor position.  In 2013, I became the Forestry Supervisor for the Village of Lombard.
