Sue Marshall



A Minnesota native, Sue got her entrepreneurial start in the real estate industry. Here she focused on real estate models that are both environmentally responsible and economically sustainable. With this passion in mind, she enrolled at the University of St. Thomas to pursue a master's degree, aiming to start a new business. During her time at school, Sue discovered how technology could be used to reduce food waste. Noticing the gap in the market for this type of socially responsible initiative, she founded NETZRO to solve this problem. Sue is driven to make a positive impact on the environment for current and future generations. Sue is a founding board member of the Upcycled Food Association.
