In 1927, William Phillips started with a small mushroom growing business in Kennett Square, PA. Before this time, mushrooms were a winter crop, in part due to temperature. William was one of the first to use ice for temperature control — making it possible for mushrooms to grow year-round — providing a significant breakthrough for the mushroom industry. Williams’s passion for growing top-quality mushrooms and his dedication to customers is what encouraged his drive for innovation. It inspired many in the area including his sons, Donald and Marshall.
