Description Established in 2002, Temecula Valley Bancorp is the holding company for Temecula Valley Bank, which operates about a dozen branches in Southern California's Riverside, San Bernardino, and San Diego counties. A Small Business Administration (SBA) preferred lender, the company also has SBA loan production offices throughout California. (In early 2009 the bank announced plans to close its SBA lending offices outside the state.) About 70% of its loan portfolio is secured by real estate, mainly in the form of commercial mortgages and construction loans. SBA loans account for nearly a quarter of its portfolio. The bank also offers standard services such as checking and savings accounts, CDs, and debit cards.
