History
The company was founded in Barstow, California, in 1931, and soon expanded to the nearby town of Victorville. Natural gas was brought into southern Nevada in 1953, and Southwest Gas began service to the burgeoning communities of Las Vegas and Henderson the following year.
On January 24, 1956, Southwest Gas Corporation became a publicly owned company. Expansion into Arizona occurred in 1957 with the acquisition of Natural Gas Service of Arizona, which served customers in Gila, Greenlee, and Pinal counties.[3]
