Promoting Beefmasters Worldwide for more than 50 Years

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.

Lasaters’ L Bar brand dates back to late 1800s

Ed C. Lasater first recorded the L Bar brand in 1893 in Brooks County, Texas. He purchased several ranches in South Texas beginning the late 1880s. By 1900, he owned 380,000 acres, known as La Mota. He introduced Brahman cattle to South Texas in 1908 and served as president of TSCRA in 1911.

In 1964, Laurie and Annette registered the L Bar brand in the northern Mexican state of Coahuila. They imported the first Beefmaster cattle into Mexico, and today Beefmasters are one of the largest registries in that country.

Setting up their cattle operations in Texas, Laurie and Annette later registered the L Bar brand in West Texas in 1972. Today their children, Lorenzo and Isabel, continue raising Beefmasters with the L Bar brand.
