History Matters: Mount Desert Island's High School Consolidation, with Raney Bench
A presentation from the Mount Desert Island Historical Society
"Explore the history of how individual towns on Maine's Mount Desert Island first united to create a regional high school. Do you wonder how big changes happen in small communities? How did islanders overcome obstacles, engage in discussions, and ultimately decide to take big risks and open a new high school? MDI Historical Society Director Raney Bench shares insights into how our small community navigated the obstacles and risks of that significant change."
