Armstrong Bank is a mid-sized community bank based in Muskogee, Oklahoma, with a footprint across Oklahoma and Arkansas. Founded in 1909, it emphasizes close ties to the neighborhoods it serves, with employees who live and work in those communities. The bank provides core retail and commercial banking services to individuals and local businesses and supports involvement with local community organizations. In March 2026 the bank expanded its footprint by acquiring five branches in the Dallas-Fort Worth area and in Waco, Texas, from First Guaranty Bancshares. This move marks a concrete step into Texas and broadens its geographic presence.
