Minn. Stat. § 50.065: OFFICERS.

Every savings bank, except when otherwise specially provided, must have a president, secretary, and treasurer, and may have one or more vice-presidents and other officers, as its certificate of incorporation or bylaws may provide. The time and manner of their election and their respective duties must be prescribed in the certificate of incorporation or in the bylaws. Only one president of record may act on behalf of the savings bank; however, additional officers may be titled president for purposes of empowering those additional officers to function as managing officers of detached facilities of banks.
