Description First PacTrust Bancorp is the holding company for Pacific Trust Bank, which offers deposit and loan services from about 10 branches in Southern California's Riverside and San Diego counties. Mortgages secured by one- to four-family residences account more than half of its loan portfolio. The bank was founded in 1941 as Rohr Employees Federal Credit Union; a handful of former Rohr executives are on First PacTrust's board of directors. Executives, directors, and employees of First PacTrust own about a third of the company's stock. In separate deals, First PacTrust is buying Gateway Bancorp and Beach Business Bank; the transactions will add another seven branch locations in Southern California.
