When Randall Grimmius, Hanford, Calf., was in junior high, he spent the summer buying a couple hundred head of dairy calves to grow. Armed with his farm upbringing and a spreadsheet, Grimmius found a niche where he could make money by filling a need.
“I got started from there,” said Grimmius who now operates Grimmius Cattle Company, a large-scale calf raising business in California and Texas.
In the last decade, they’ve entered the Angus seedstock business.
By 2000 the industry had changed. Day-old dairy calves were marketed right off the farm, and Grimmius saw an opportunity to do it differently.
“Information, quality of a calf, and God — that was our three principles of how we try to build our deal,” he said.
Today they take in nearly 2,000 head each day, employing 1,000 people and returning premiums to those who supply quality calves to them. His team’s goal is to make that transition from home dairy to calf ranch as seamless as possible.
