In her role as EY Americas Climate Change and Sustainability Services (CCaSS) Deputy Americas Leader and Global Environmental Health and Safety (EHS) Advisory Solution Leader, Chicago-based Jessica Wollmuth has been instrumental in managing and recruiting a rapidly growing team that has expanded from 100 to more than 300 US CCaSS team members in the past 18 months. 

Jessica is responsible for driving business growth and works with a wide spectrum of clients, ranging from start-ups to Fortune 100 companies. She is a dedicated and inspiring leader, guiding cross-functional and cross-cultural teams to develop unique solutions using expertise in decision analytics, group facilitation and technical expertise in environmental and energy management.

Over her nearly 30-year career, she has accrued vast experience across a diverse set of sectors and industries, including apparel, consumer goods, agribusiness, power, mining, chemical, and oil and gas.
