As Arboretum Director, Glenn Dreyer oversaw all department functions, including education, planning, land management, collection curation, research and fund raising. He was also an adjunct professor of botany and was an executive director of the College's Goodwin-Niering Center for the Environment. His professional and research interests have to do with the interface between horticulture and ecology.

As Arboretum director, Mr. Dreyer reported to the Dean of the Faculty, and worked closely with faculty and students in the life sciences and a variety of administrators, including the Director of Facilities Management and the Supervisor of Grounds.

Glenn Dreyer started working for the Connecticut College Arboretum in a landscape maintenance capacity while still a graduate student in 1982. The next year he became Assistant Arboretum Director under William A. Niering. In 1988 he was appointed Arboretum director.

He is the author of the books Connecticut's Notable Trees and Greening Connecticut Cities & Towns: Managing Public Trees and Community Forests, and a variety of professional publications on invasive species and vegetation management.

Mr. Dreyer serves on the Connecticut Urban Forest Council and the Connecticut Tree Protection Examining Board. On campus he is a member of the Environmental Model Committee and the Facilities and Land Management Committee.

Off campus Glenn enjoys playing the great highland bagpipe and Scottish Smallpipes and helping his wife Wendy with her Australian shepherd dogs.

"Here at Connecticut College we are engaged in inventing cooperative, ecologically sensitive land management. I believe our results will be a model for other institutions." - Glenn Dreyer
