As a child, Sheryl O'Loughlin was best known for rushing everywhere and being too impatient to pour milk into a glass before drinking it. As an adult, Sheryl is no less eager. She served as the CEO of Clif Bar, where she introduced the world to Luna bars; she was the cofounder and CEO of Plum Organics; and she is currently CEO of REBBL super herb beverages. One of her favorite roles was mentoring budding entrepreneurs when she was the executive director at the Center for Entrepreneurial Studies at the Stanford Graduate School of Business. With her book, Sheryl is able to share her advice with a wider group of current and aspiring entrepreneurs all at once, which delights her because, well, it's faster. And that means more time for drinking wine at her Santa Rosa home, and hanging out with her husband and two sons.
