Bob Salesi, 68, is a retired chemistry teacher from Hampden Academy who now lives in Penobscot. He has a loyal clientele of repeat customers who rely on him for his tree work as a registered arborist, a job he approaches the old-fashioned way. He doesn't use a bucket truck, but goes 50-60 feet up into trees with a chainsaw and a series of ropes that he swings from while taking down limbs. STAFF PHOTOS BY JAMES STRAUB
