      From the classroom to the trees

      Greg Ranallo has been working with trees since he was 19 years old — a passion that began long before it became a profession. After earning a master's degree in education and teaching high school social studies in his native Minnesota, Greg ultimately followed the calling he'd had since boyhood and built Teacher's Tree Service into one of the Champlain Valley's most trusted arboriculture companies.
