Pioneer breeders of performance cattle, Dave and Yvonne Hinman of Hinman Angus, have raised registered Angus cattle since 1973. The couple and their daughters, Jill and Heidi, ran Hinman Angus in Willow Creek, Montana for over 25 years. It was there in 1988 they had their first production sale, joining with Bill and Jennifer Davis and two other couples as the Performance Breeders, a group that worked together until 2008 to market registered Angus seedstock.

In 2000, Dave and Yvonne made the move to “good old cow country” near Malta, Montana to lease an 8,000-acre ranch and later purchase land in the area. In Malta, they have worked alongside daughter Heidi and son-in-law Billy Lulloff for many years, mentoring them and now their grandson Tyler Lulloff to assume more responsibilities on the ranch. Together they continue to produce high-quality, reputation cattle as Hinman Angus and distribute their signature, bright yellow-covered sale books annually. 

As leaders in the breed, Dave served on the American Angus Association Board of Directors from 2017-2023. Yvonne served as president of the American Angus Auxiliary in 1999-2000 and was honored as the Distinguished Woman Award in 2007. In 2005, the Performance Breeders were recognized with the Certified Angus Beef (CAB) Seedstock Commitment to Excellence Award. Each morning, Dave and Yvonne keep the end goal in mind as they look out their front windows to see the CAB logo adorning their branded barn, the 50^th in the series.
