A longtime supporter of Concord Academy, Marion began her first term on the CA Board of Trustees in 1986 and continued until 1997, spending the last six years of that term as treasurer. She stayed off the board for only a year, returning as president and overseeing a capital campaign and a head search process, which resulted in Jake Dresden joining CA. To honor outgoing head Tom Wilcox, Marion raised more than $2 million for the Wilcox Leadership Fund. She stepped down as president in 2002, but stayed on the board until 2003, serving on various committees and allowing a smooth transition for the next board president, Henry P. Becton Jr. Marion became a life trustee in 2002. She earned a BA degree in romance languages from Princeton and a PhD degree in French from Yale. At CA, she taught, coached squash, served as a house parent in Phelps House, and was an assistant director of admissions from 1973 to 1974. After earning her PhD degree in 1980, she taught French at Yale and became a dean of one of the residential colleges there. Shortly thereafter, she began her career in international banking by joining J.P. Morgan in New York. Marion has served on various boards in Maine, including that of the Gulf of Maine Research Institute and the Portland Museum of Art. Marion still remains very involved with CA. She has served as a leadership solicitor, a class agent solicitor, a phonathon caller, and a member of her 40th-reunion committee. She has remained on CA’s investment subcommittee since her departure from active board duty. Marion lives in South Freeport, Maine, with her husband, Corson Ellis, CEO and founder of Kepware Technologies in Portland, Maine. They have a daughter, Linden, and a son, Francis.
