Mark Eisele lives in Cheyenne, Wyoming, where his family runs Red and Black Angus cow-calf pairs, retained yearlings that sell into branded programs, and a custom haying operation on the historic King Ranch. 

The ranch runs cattle on both privately owned and public lands with state and federal grazing leases. Eisele understands the delicate balance that is protecting private property rights and maintaining access to public lands while increasing numbers of people want to experience the beauty of the West. The King Ranch was recognized in 2015 for the Leopold Conservation Award and Wyoming Stock Growers Environmental Stewardship Award. Eisele also served as the 51st Wyoming Stock Growers Association president. Eisele has been heavily involved in the NCBA since 2009 when he sat on the board of directors before serving on the Animal Health and Wellbeing Committee for eight years. Since his start with NCBA, Eisele has served many roles including serving on the Nominating Committee, Public Lands Council – Legislative Session, Environmental Stewardship Award Wyoming (Region V), and being a Political Action Committee (PAC) donor.
