Tiemann Land and Cattle was established in 1981 by Rob Tiemann in Pflugerville, just north of Austin, Texas. In 1981, Pflugerville was a rural farming and ranching community. Today, it is a rapidly growing suburban area. The original ranch is now the site of the Blackhawk residential subdivisions.
The ranch office remains in Pflugerville. The base of ranch operations has been moved to Rockdale in Milam County. Operations also have expanded to include summer grazing in Springer, New Mexico. In addition to stocker cattle, the ranch raises for sale fallow deer, blackbuck, red deer, elk, zebras and addax.
In late 2001, Rob and his wife Carrie acquired their first cutting horses. Today, the cutting horse operation is based in Rockdale and is under the direction of Jonathan Rogers. The cutting horses are moved to Springer, New Mexico during the summer for training. Tiemann Land and Cattle also maintains a training facility in Millsap, near Weatherford, Texas.
