Based in Clovis, N.M., Allsup's Convenience Stores is ranked as New Mexico’s top privately owned corporation.

With more than 300 stores in 160 small towns and on highways in New Mexico and West Texas, Lonnie and Barbara Allsup have long been recognized as innovators in the industry since opening their first location in 1956, then-known as “Lonnie’s Drive in Grocery” in Roswell, N.M. Often cited as the “mother and father of the modern day convenience store,” they were one of the first to offer 24-hour self-service gasoline and were early innovators selling cooked foods from burritos to barbecue. Allsup’s stores are known for their deep-fried burritos and eggrolls, made fresh at the stores.

In addition to the c-store chain, the Allsups own a petroleum jobbership, software-development company, radio stations and world-championship cutting-horse ranches in Texas and New Mexico. “At Allsup’s, being the best means working hard all the time to serve and please our many customers,” the company mission states.

Allsup’s is a 24-hour chain that sells fuel under the Alon, ConocoPhillips, Exxon and Allsup’s private-label “On the Go” brands. The company’s main competitors are Circle K, Stripes, Valero and 7-Eleven.

Allsup’s has one-to-three new stores planned, with the chain constantly remodeling stores.
