Allegiance Bancshares, Inc. is a Texas corporation and registered bank holding company headquartered in Houston, Texas. Through our wholly-owned subsidiary, Allegiance Bank, we provide a diversified range of commercial banking services primarily to small to medium-sized businesses within the Houston region, professionals and individual customers. We believe the size, growth and increasing economic diversity of the Houston region, when combined with our super-community banking strategy, provides us with excellent opportunities for long-term, sustainable growth. Our super-community banking strategy, which is described in more detail below, is designed to foster strong customer relationships while benefitting from a platform and scale that is competitive with larger regional and national banks. We believe this strategy presents a significant market advantage when serving small to medium-sized business customers and further enables us to attract talented bankers.
As of December 31, 2018, we operated 28 full-service banking locations, with 27 bank offices and one loan production office in the Houston metropolitan area and one bank office location in Beaumont, just outside of the Houston metropolitan area. We have experienced significant growth since we began banking operations in 2007, resulting from both organic growth, including de novo branching, and three whole-bank acquisitions, most recently Post Oak Bancshares, Inc. As of December 31, 2018, we had total assets of $4.66 billion, total gross loans of $3.71 billion, total deposits of $3.66 billion and total shareholders' equity of $703.0 million.
