History & Mission

First Seacoast Bank, headquartered in Dover, New Hampshire, has served residents of the Seacoast area of New Hampshire since 1890. Opened under the name of Dover Co-Operative Savings Fund and Loan Association, its original meeting was held in the Cocheco Hose Company on First Street, where the Municipal Parking Lot is presently located.

For over 65 years, the Bank, known as Dover Co-Operative Bank and later as Dover Federal Savings and Loan Association, was housed in the Walker Block at the corner of Locust and Washington Streets. The present main office at 633 Central Avenue was constructed in 1972. The bank’s name was changed to Federal Savings Bank in 1983 to reflect a growing customer base in areas outside of Dover.
