Summer Sire Directory 2025
We’ve spent the past year doing what we love—traveling across the country, studying the Angus breed, and digging deep into the cattle that perform best in our program. Every bull in this lineup reflects that work. This summer, we’re featuring a young group of sires we believe have what it takes to compete with the best. They’re not proven yet, but the foundation is there—strong pedigrees, standout phenotype, and the kind of data that gets your attention. We’re excited to watch them step up—and even more excited to share them with you.
Also, take a look at our new donor heifers. We’re mating them to our best bulls with one goal in mind: building the future of our herd, one elite pairing at a time.
