Welcome to Walnut Hill Farm! Founded in 2013 by John and Mary Lee Calihan, the farm provides the freshest and most flavorful produce, as well as a local food source, for both family and friends. The farm is located in south central Wisconsin, near the town of Brodhead. With the addition of a barn and greenhouse in 2014, the farm enjoyed its first harvest with a wide variety of vegetables. In 2015 the Calihans expanded the farm by adding an herb garden, blueberry and strawberry plantings and a small apple orchard.
