Founded by Laurence M. “Laurie” Lasater, eldest son of Beefmaster creator Tom Lasater, Isa Beefmasters has promoted the breed around the world since 1964. Laurie, and his
wife, Annette, introduced Beefmasters into Mexico in 1964 and operated there for 10 years. In 1972, they established a cattle enterprise in San Angelo, Texas, and it was incorporated in 1983 as Isa Cattle Co., Inc., (pronounced EE-sa). In 1993, their son, Lorenzo, joined them in the business.

In 2014, Lorenzo and his sister, Isabel Lasater Hernandez, formed Isa Beefmasters, LLC, to carry on the family tradition of raising performance Beefmaster genetics for the beef industry worldwide. Lorenzo serves as president of the company and oversees all aspects of operations. Isabel handles the marketing efforts, including the print advertising and website design.

These six points are the cornerstones of Tom Lasater’s cattle-raising philosophy and the means by which all of our cattle—L Bar Beefmasters—are evaluated.
