Champlain Bank Corporation is the holding company parent of Champlain National Bank. The Bank itself was formed in 1959 as the result of the merger between Lake Champlain National Bank in Westport and Essex County National Bank in Willsboro. Lake Champlain National Bank dates from 1909, and Essex County National Bank commenced business in 1923. Additional offices of the combined bank were opened in Elizabethtown in 1961, Crown Point in 1973, Keene in 1987, Plattsburgh in 1992 and 1999, and Champlain in 1996. Thus, the present bank has a long history of service to the people of Essex and Clinton Counties
