Our History

Gretna Machine Shop was founded by Jose Benjamin “Benny” Pérez and his wife, Ninfa Pérez. Benny came to the United States from South America in 1967 bringing the kind of hopes, dreams and ambition that so many others bring with them when they arrive in the U.S. seeking the “American Dream.” After 15 years of working as a machinist, Benny and his wife decided to venture out on their own. They had a simple goal: to build a successful business based on hard work, honesty and integrity. Benny and Ninfa opened Gretna Machine Shop, Inc., in 1980. They named it after the town in which their daughters were born: Gretna, Louisiana.


Our Founder

Jose Benjamin “Benny” Pérez

Benny graduated as a machinist in 1961 from the Industrial Technical  Institute of Pascual Bravo in Colombia. After immigrating to the United States in 1967, he began his career as a machinist in Avondale Shipyard in Louisiana. He later became a master machinist and inspector at Baker Hughes in New Orleans. In 1980, Benny moved his family to Houston to pursue opportunities in the oil and gas industry by opening Gretna Machine Shop with his wife, Ninfa. Benny was the backbone in instilling Gretna’s core values, which are still in practice today.
