Western Alliance Bancorporation

A bank holding company serving small and middle-market businesses, Western Alliance lends to companies through Western Alliance Bank and its mortgage arm AmeriHome, while its DST unit handles digital payments for the class action legal industry. Founded in 1994 in Las Vegas (relocating to Phoenix in 2010), it grew by buying up local Western banks. In 2025 it folded six former brands—Alliance Bank of Arizona, Bank of Nevada, Bridge Bank, and more—into the single Western Alliance Bank name.
