Dustin Dahlstrom
Sales Representative, East Central US
Dustin was born into the cattle industry, having grown up helping with the family cow/calf and row crop operations while also working at his parents’ veterinary practice.
After receiving his Animal Science degree from Oklahoma State, he served as an assistant herd manager for the OSU Center for Vet Health Sciences Ranch and later as the Operations Manager for Circle A Feeders, a 5,000-head feedlot in north-central Missouri.
A unique part of Dustin’s cattle experience comes from his years helping with the family vet practice, where he would assist in the processing of nearly 40,000 head a year at the Joplin Regional Stockyards. Growing up in a veterinarian’s family has given Dustin an inside perspective on the economics of running a successful and sustainable business.
