Rainier Bancorp expanded into Alaska with the purchase of Anchorage's People's Bank & Trust in 1983 and into Oregon with the purchase of Gresham's Mount Hood Security Bank in 1986, expanding further in Oregon in 1986 with the government-assisted purchase of Portland's failed Lincoln Savings & Loan Association.
