Our Story

Welcome to Grass King Cattle, where our deep-rooted dedication to family, sustainable farming practices, and the highest-quality meat not only defines who we are, but invites you to become a part of our legacy.

Welcome to Grass King Cattle

Jim and Karen Zezas own Grass King Cattle Company LLC in Buffalo, Wyoming. Both native to Wyoming, Karen grew up on a ranch near Hulett, while Jim worked on his family's homesteaded ranch. They married in 1985 and have a son in Denver and a daughter in Casper. They've been involved in farm-to-table sales for over 34 years, starting the Buffalo farmers' market. In 2015, they expanded with Grass King Cattle Company LLC, offering regional produce and their own meat products. Their commitment: providing consistent, quality meats, reflecting the "Grass King Way".
