During 1977-78 some progressive Susanville residents banded together to establish an independent community bank. The last time this occurred was in 1912, with the formation of the Lassen Industrial Bank. Anyhow, in 1978, the Sierra Security Bank was formed. The location of the new bank was at 100 Grand Avenue, Susanville, now the home of the Lassen County Times. Sierra Security’s bank building was a portable structure. In November, 1978 the new 4,200 square foot bank arrived in six sections, from Sunnyvale, California where it had been used by De Anza Bank.
