Raising Calves, Mentoring Kids and Coordinating Logistics — Randall Grimmius on Raising Beef and Entering the Angus Business

What happens when the beef and dairy worlds intersect? Randall Grimimus, California cattle feeder and Angus breeder, joins the podcast to talk about the ever-evolving beef-on-dairy sector and how Angus fits into it. From raising day-old calves to scaling his family operation, Grimmius shares how data, genetics and relationships have built his business. He is grounded in faith and guided by a strong desire to do the right thing for his calves, his employees, his suppliers and his customers. In this episode you’ll learn about everything from his young entrepreneurial ambitions to how he listens to God’s call. HOSTS: Mark McCully and Miranda Reiman  GUEST: Randall Grimmius   Randall Grimmius is the owner of Grimmius Cattle Company, a family-owned and operated livestock business he helped build from the ground up alongside his father, Tom Grimmius. What started as a cattle feeding and trading business has grown into a fully integrated operation spanning seedstock genetics, dairy, cow-calf production, calf raising and cattle feeding across California and Texas — with five ranches; capacity for 300,000 head; more than 1,000 employees; and additional cattle fed through some of the industry's most respected feedyards in Kansas, Texas, Nebraska and Colorado. Away from the operation, Randall and his wife, Beth, have been married 34 years. Together they have four daughters, eight grandchildren and have provided guardianship to 12 additional children over the past 15 years. He remains deeply committed to faith, family and the values that continue to guide the company. SPONSOR:  Angus Media: Are you ready to level up your herd’s genetics?
