Other plans for his retirement include a "honey-do" list and spending time with his grandchildren. "We want to see them; we want to enjoy them while we still have our health," said Mulligan.
However, Mulligan won't be out of the educational field for good, as he's hoping to do some work at the State University of New York at Plattsburgh.
"I'll keep my feet wet, so to speak, in education," Mulligan explained. "Teaching a course or two ... and also probably supervising student teachers."
During the 2010-2011 school year, John Fairchild, a former principal from Plattsburgh High School, will take over Mulligan's position.
"I think John being a graduate from here, I think it will be a good fit for [him]," he said.
