Producer Spotlight
Welcome to the Producer Spotlight, where each month we'll showcase our farm members.
Jonathon Hallock
MarBec Dairy in Gilmanton, Wisconsin, began in 1993 when Marty Hallock set out to build a farm grounded in leadership and education. Those values have shaped MarBec into what it is today, a thriving dairy home to 1,250 cows. Marty’s son, Jonathon, returned to the farm full-time in 2013 and became a partner in 2018. Now, he’s continuing that legacy alongside his father and adding his own vision for growth and teamwork.
Tom and Joan Oberhaus
For more than 40 years, Joan and Tom Oberhaus have operated Cozy Nook Farm in Waukesha County, where they milk about 80 cows, along with a thriving agri-tourism business featuring pumpkins and Christmas trees. “Everyone wants an important job in life, and we feel we have an important job producing food and fiber for America,” Tom said.
Tim and Sandy Keller and Mark and Kareen Keller
Kellercrest was formed in the late 1960s when Daniel and Jeanne Keller purchased two registered Holsteins. In 1972, they bought a registered calf for their 10-year-old son Tim. Suzie was the first calf the Kellers purchased from John Hamilton of Verona, Wis. Two years later, Tim purchased another registered calf from John; today, several members of the herd trace back to these early calves.
