Overview
Sioux Nation Ag Center in Kimball is a large animal veterinary clinic staffed by a veterinarian, three veterinary assistants, an office manager, and a secretary. We work in all segments of the beef cattle industry, primarily providing service to beef cow-calf clients within a 30-mile radius, as well as local feeders and growers. We also support the Kimball Livestock Exchange, LLC, which has weekly feeder sales year-round and additional bred cow and pair sales during the winter and spring months
There are certainly many ways to succeed in business. At Sioux Nation Ag Center, we’ve stuck with the one Marvin Swenson chose when he established this company in the back corner of a Sioux Falls hardware store in 1960. It’s not complicated. We simply listen to our customers, understand their needs, and figure out the best way to meet them. Marvin was an outstanding animal health salesman, and the business quickly outgrew their corner and took over the building. Growth continued, and Marvin moved the business to a building at the current home location on Cliff Avenue. His reputation spread, and the business grew, thanks in part to a radio show that customers still remember to this day. When Marvin died suddenly in 1977, son Scott came home from California to help his mother Marcella run the business. Scott’s brother Brad added his expertise as a commodity broker to the business a few years later. Over the years, Scott added more services and products to the animal health line, buying into—and eventually purchasing – the Farmers Feed & Supply feed mill in Boyden, Iowa. The next step for Scott was the creation of the Ag Center business model, which brought together animal health products and feed with the expertise of staff nutritionists and veterinarians. The Swensons also discovered that in order for Brad to hedge the board most effectively, many of their customers needed to get a better handle on their break-evens. That led to the development of a detailed financial management system for Sioux Nation livestock producers. That combination of animal health and feed products, supported by nutritional, veterinary and financial services is what makes Sioux Nation Ag Center unique in the industry. Today, Scott’s sons, Joe and Brian, are the third generation heading up the company. Joe is the CEO of Sioux Nation Ag Center and Brian oversees the Sioux Nation Pet Clinic that has grown steadily at the Cliff Avenue location. Sioux Nation services are now available at 11 locations in South Dakota and Minnesota, thanks to the focus on keeping our customers at the center, treating them right, and building everything else around that principle
