Biography

      Lyell Clarke is the President and CEO of Clarke and all affiliated companies. Lyell has spent more than 25 years in the Entomology field. He earned his Bachelors of Science in Entomology from the University of Kentucky, and went on to receive his PhD in Entomology from Iowa State University. He began his career with Clarke in 1986 as a Control Consultant. After gaining a solid grounding in the business, he became Vice-President for the company. In 1996, upon his father’s retirement, he stepped into the role of President/CEO. In 2008, Lyell led the company in a re-visioning of the company based on a platform of sustainability. His personal passion for what sustainability can mean propelled Clarke to redefining itself as a company with greater purpose. Significant goals were set and achieved, enabling three sustainability reports to be produced to Global Reporting Initiative (GRI) criteria and review. His vision is creating a new perspective on the role and change that a small to medium size company can make in society. Lyell serves on two advisory boards: The Fowler Center for Sustainable Value at the Weatherhead School of Management at Case Western Reserve University, Cleveland, OH, and privately held Weigel's Farm Stores, Inc. based in Powell, TN. Lyell and his wife Kathy, have five children. Oldest, John works in marketing for craft beer manufacturer, New Belgium Brewery. Katy is operating a start-up organic farm and is building a network serving Chicago metro area market outlets and restaurants. Robert works as an operations supervisor out of Clarke’s Roselle, IL service center. In 2006, the family made the decision to expand and traveled to Russia in order to adopt Joseph. Then, in November 2010, Lyell and Kathy adopted another son, Timothy, who was 2 years old. With two young elementary-aged children in the Clarke household, Lyell and his wife Kathy are re-experiencing the rewards (and exhaustion) of being parents!!
