For 25 years, we were a commercial cow/calf producer, and have been uniquely aware of the challenges that cattlemen in the ranching and farming industries have dealt with for decades. Our search for creating the perfect female that thrives in our environment on limited resources and gives the most production, while maintaining her physical condition and increasing profitability, has always been our goal.


Our focus will always be on fertility and the ability to raise a high-performing calf that is stylish and sells well year after year. This quest has led us to pursue maternally driven genetics.


We've been extremely fortunate to have the opportunity to own, in our opinion, two of the best cow-makers of all-time, SAV Renown 3439 and SAV 004 Density 4336. Our cow herd will be heavily influenced by these two breed legends for generations to come.
