For more than 60 years, the Dunn Ranches registered angus herd ran on high desert land in central Arizona. At the time, it was the oldest registered angus herd in Arizona and one of the oldest in the Southwest. Dunn Ranches held an annual bull sale in Arizona for many years.
As the time came to retire in 2020, William A. Dunn Jr aka “Bill” and his wife Becky made the tough decision to split their herd. Part of their herd moved to Northern Colorado with their grandson Buster and his wife Kassidy, and the other part moved to East Texas with their daughter Sam and her husband Chris, operated as Misita Cattle Company.
I, William A. Dunn IV aka “Buster” am beyond proud to not only share my grandfather’s name, but the years of genetics that we built for this herd. My wife, our two boys, and I live in Pierce, Colorado, and are honored to offer our bulls at our inaugural Colorado bull sale. In 2021, our oldest son William A. Dunn V aka “Cinco,” was just a newborn when our first semi load of cows arrived from the ranch in Arizona. It was the middle of the night during a blizzard, and they were very unhappy leaving the Arizona heat behind them. We have since expanded our herd three times from our original bunch, by holding back our best heifers as well as adding heifers from the Misita herd. In addition to our growing herd size, we also welcomed a baby boy, Cash Dunn, in the fall of 2022.
With the continued help from Bill and Becky, and their substantial knowledge of cattle and conservation, we have been hand selecting the genetics of this herd, securing leases, creating the most optimal feed plans, and learning everything we can. Not only do we focus on best serving our herd, but the land we graze as well. We truly thank God each and every day we are able to learn and live this lifestyle.
2025 is the first year that Dunn Ranches’ bull sale will be held in Northern Colorado. Up for offer we have 46 coming-twoyear-old registered black angus bulls. All of our bulls have been range developed at an elevation of 9500’ and pap tested by Dr Holt at this elevation. This is in Jefferson, Colorado, where the bulls enjoy “summer camp” each year. This is part of the reason we are very confident in their genetics, abilities, and the positive impact they will leave in your herd for years to come. You will notice that most of the bulls are very low birth weight, calving ease bulls. Also, most have above average $EN value, which is a measure of maternal efficiency. These traits have been a high priority for us for decades, since the southwestern ranges demand it.
We want to thank our incredible group of friends and family that continue to make this operation run smoothly. Without all of you and God by our side, we would never be where we are today. Each night as a family we thank Him for “the cows, the babies, and the rain. Amen.”
We want to extend an invitation to visit our ranch, anytime, for a viewing prior to our sale. Our bulls are guaranteed 100% as they have been for 60 years, and we offer free delivery to anyone who purchases a bull from us. We hope to see you all on Tuesday, April 22nd, for our inaugural Colorado bull sale.

I am proud to assist the entire Dunn family in preparations for their inaugural Colorado bull sale. The Dunn’s have deep roots in the cattle business and have been raising Angus cattle and having sales for many years. This will serve as their first event hosted in Colorado by the next generation, Buster and Kassidy Dunn. It is always a pleasure to assist any young family that is wanting to make a go of the cattle business, I appreciate their work ethic and desire to carry on the family tradition.
These bulls are a valuable commodity in today’s world. We will be offering you 40 plus full two-year-old bulls that are fully PAP tested and developed at 9,500 feet. They have been fed and managed to offer plenty of longevity and can survive harsh conditions. The breeding behind this set focuses on carcass quality and feed efficiency, two attributes that are being heavily rewarded by today’s market.
The Dunn family are great people to deal with, and will stand behind their product 100%. I invite you to either join us on sale day or preview the bulls ahead of time. If myself or any of the sale staff can be of assistance, please do not hesitate to reach out.
See you on sale day,
