American Business Bank (ABB) was a U.S. commercial bank headquartered in Los Angeles, California, founded in 1998. It specialized in providing a comprehensive range of financial services to middle-market businesses, business owners, and professionals throughout Southern California. Key offerings included commercial and industrial loans, commercial real estate loans, and a variety of deposit products. Known for its relationship-based banking model, ABB focused on delivering personalized service and local decision-making. In November 2023, American Business Bank was acquired by Banc of California, N.A. This strategic move was aimed at creating a larger, more robust business banking franchise in the region.
Served as the central hub for executive leadership, strategic planning, administrative operations, risk management, and core banking support functions before its integration with Banc of California.
The headquarters was located in a modern, Class A high-rise office building typical of the Century City skyline, offering a professional environment and convenient access for business clients in the Los Angeles area.
The work culture at American Business Bank was characterized by a strong client-first ethos, professionalism, and a commitment to providing expert financial advice and responsive service to its business clientele. It fostered long-term relationship banking.
The headquarters was significant as the operational and strategic core of American Business Bank, directing its services across Southern California and representing its established presence in one of the nation's largest business markets.
Prior to its acquisition by Banc of California, American Business Bank did not have an international or global presence. Its operations were exclusively focused on serving the Southern California market, encompassing Los Angeles County, Orange County, the Inland Empire (San Bernardino and Riverside Counties), and the San Fernando Valley. The bank's strategy was centered on deep regional expertise and building strong, local relationships with middle-market businesses within this geographic footprint.
