Glendenning Farms was founded in 1986 by Rex and Sherese Glendenning

Rex and Sherese Glendenning began breeding Texas Longhorn cattle after trading part of a real estate commission with J.B. Hunn for three young longhorn heifers. As a history aficionado, Rex became interested with the history of the breed, as did his wife Sherese. Even though the couple had purchased several Longhorns at events such as the Southfork Longhorn Spectacular, they were still in need of a true herd sire. Shortly thereafter, the Glendenning's successfully AI'd Colorado Cowboy to straight Wright cow named Inex of Acampo.

The Beginning of Something Great

Now that the Glendennings had a true herd sire, they were able to breed GF GMan in 1991. At the time, he was the longest horned bull on record. GF GMan went onto influence the breed with progeny such as Gunman and many others. GF GMan became the anchor that helped the GF brand become one of the premier longhorn breeders in the industry for over 32 years now.

It wasn't long before GF GMan out produced himself to sire the Great GF Heavy Hitter, who took GF GMan's place as the longest horned bull. GF Heavy Hitter's tip-to-tip measurement was recorded at 87 3/4 inches. GF Heavy Hitter would keep the title of longest horned bull for several years.

The bloodlines of both GF GMan and GF Heavy Hitter make up the foundation of the Glendenning Farms' brand. Glendenning Farms could not pull off the complete trifecta internally and had to go outside the GF brand to acquire the greats bull in the industry - Drag Iron. Drag Iron was purchased in 2015 from Dickson Cattle Company. Drag Iron became the premier herd sire at Glendenning Farms and brought the GF brand back into the industry spotlight. The Glendennings believe that Drag Iron encompasses the best in Texas Longhorn genetics.

The GF brand's breeding program spans over three decades. Throughout these decades, the GF brand has stayed true to breeding authentic, iconic, true Texas Longhorns. This is evident through Longhorns such as Archers Possum Eyes, GF Awesome Yates, GF Measles Gal, and Awesome Rosebud who make up the GF brand's cattle foundation.
