Champlain National Bank’s history dates back to 1909 when Lake Champlain National Bank began operations in Westport, NY. The Champlain National Bank that exists today was formed in 1959 as the result of the merger between Essex County National Bank in Willsboro, NY (founded in 1921) and Lake Champlain National Bank. Additional branches were opened in 1961 in Elizabethtown, 1973 in Crown Point, 1987 in Keene, 1992 and 1999 in Plattsburgh, 1996 in Champlain, 2006 in Lake Placid, and 2017 in Saranac Lake.
