About Us

Diamond M Cattle Company was started by Mark Mueller with the help of his father running an assortment of commercial cows, selling a few club calves, while still in college at Kansas State University. While at K-State, Mark met his wife, Lori. They were married in 1985 and started a family soon after with son Matt and twin daughters, Ashley and Lindsey. All of which attended and graduated from the same school where their parents met.


All of the kids have been and still are active in the farm's cattle operation. Diamond M's first sale, The Showcase, was with long time friends, Greg Fisher Cattle, Pelton Ranch and Gartens.


DMCC is best known for some of the greats in the Maine-Anjou breed and truly helping many other breeders improve their programs with cattle that wear the DMCC prefix.


Cattle that stand the test of time are at the heart of the DMCC program.
