Established in 1923

One of San Antonio’s oldest and largest electrical contractors, Nathan Alterman Electric Co., Ltd. commenced operations in 1923 when Nathan Alterman purchased an existing company at the age of 24. During the 1930s and 1940s, downtown remodeling became the mainstay of the business.
