I started working at the Arnold Arboretum as a grounds intern, 1971-72. Following that experience, I worked for several other companies before returning to the Arboretum in 1979. I have held various positions in my thirty-plus years here, including 10 years as an arborist. Currently, my work focuses on Peters Hill and various areas of this historical landscape. I also maintain my own tree care and landscape company.
