EAT BEEF
CONSERVE PRAIRIE
Grass-fed.
Grass-finished.
Prairie-friendly.
Our cattle graze native grasses and prairie plants on hills that used to sit at the bottom of an ancient sea. This geology is the foundation for the Flint Hills—the world’s last remaining intact tallgrass prairie landscape, which our family (and cattle) help conserve.
