Southside Bancshares Inc.
A Texas community bank holding company, Southside Bancshares runs Southside Bank, offering consumer and commercial loans, deposits, and wealth management and trust services across dozens of branches in East and Southeast Texas and the Dallas-Fort Worth, Austin, and Houston areas. It was founded in 1960 as Southside State Bank, so named because its first office sat on the south side of Tyler, Texas, serving the city's southward expansion. The bank famously started with just ten employees and a single suburban branch.
