Bob (Jr.) and Jim Sitz of Harrison and Dillon, Montana, lead Sitz Angus as its third generation. They labored alongside their parents Bob (Sr.) and Donna as young men, growing a passion for Angus cattle and the cattle business. In their 20s, they chose to manage the ranch alongside their mother after the untimely death of their father in 1989. Together, they guided the ranch through some lean years that included a mature cow dispersal and subsequent herd rebuilding.  

In the decades since, they have expanded the ranch from a single location in Harrison to three properties, and they have prioritized customer relationships, adopted new technologies like embryo transfer and genomics, and improved the quality of their cattle. Sitz Angus sires consistently claim spots in annual lists of the top 25 sires for breed registration, and their reputation for being a high-quality source of maternal genetics persists. As leaders, Bob serves the Montana Stockgrowers Association in addition to being an active member of the American Angus Association. Jim followed in his father’s footsteps, serving on the American Angus Association Board of Directors from 2009-2016 and as president in 2016. 

Today, Jim and Bob, along with Jim’s wife Tammi (Huntsman), run Sitz Angus with their families. Jim also markets customers’ cattle as a representative with Northern Livestock Video Auction. The brothers continue to be long-term supporters and collectors of performance data, especially with the pulmonary arterial pressure (PAP) EPD and as a MaternalPlus^® herd.
