Our Team

Family Owned and Operated

The Mannix Ranch is currently owned and operated by members of the third, fourth, and fifth generation. Darlene Mannix and her late husband Bert passed the ranch down to their three sons - David, Randy, and Brent - who along with their wives - Peggy, Mo, and Stacey - have managed the ranch since 1980. Recently, four members of the fifth generation have come back to the ranch to work full time and the interest continues to grow from others who come back to help during the summer months. We feel lucky to be confronted with the challenge of keeping up with a family interest in the business and strive to set a precedent for what sustainable and economically viable multi-generational ranching can look like in Montana today.

David is the oldest son and second of five in the fourth generation. His wife Peggy helps manage the ranches books in addition to watching three of her grandkids a few days a week. Randy has long managed livestock, irrigation, and infrastructure on the Spieker ranch, as well as the Raymond ranch, which was where Darlene’s father, Newman Raymond grew up. Randy also has a degree in forestry and spends a significant amount of time in the winter managing the ranches timber and hand harvesting a small amount of timber for boards and firewood. Randy’s wife Mo works off ranch as a speech pathologist during the school year. Brent Mannix, youngest of Bert and Darlene’s family has been the homestead chief of the original Mannix homestead. Aside from managing the infrastructure and irrigation on the main homestead brent helps build and maintain infrastructure and machinery ranch wide. His wife Stacey teaches in Lincoln, but also spends a significant amount of time helping on the ranch, especially on horseback for cattle drives.
