Security State Bank opened its doors on Northwest Chehalis Avenue in 1903. Their first office was in a building owned by C.W. Long (now Visiting Nurses Thrift), before moving across the street to the two-story brick building which was constructed in the early 1900s. The original incorporators of the bank were C.W. Long, W.D. Richardson, J.W. Reynolds, E.P. Churchill and Arthur S. Cory. Three of the key men who guided the growth of the bank through most of its history were John Alexander, Sr., J.T. Alexander, a brother, and William M. Luebke who was J.T. Alexander’s son-in-law. Since 1910, only four individuals have served as president of Security State Bank.
