"We scoured the upper echelons of corporate America to find the most significant women driving innovation in the U.S. – and adding major dollars to the bottom line in the process," says Cynthia Good, founding editor of PINK. "These 15 women will soon claim the national spotlight, having birthed new generations of products and services – creating and sustaining change that continues to transform their organizations."

Duren is being honored by PINK for her vision in creating the Express Lane food products train during her tenure as vice president and general manager, Agriculture Products for the nation’s largest railroad. This reflected a huge market opportunity that had long been abandoned by the railroads. Following that was the introduction of Union Pacific’s perishable unit train – taking a full trainload of perishables from Washington State to New York. It was also during her role leading the Agriculture Products group that Union Pacific engaged the emerging ethanol opportunity helping the company proactively build the network to support ethanol rail delivery.

Today, Duren oversees Union Pacific’s marketing and sales activities for chemical and petroleum industries. During her career, she has held a variety of positions in the finance and marketing and sales departments with Union Pacific since joining the company in 1985.

Duren is a graduate of Creighton University in Omaha, where she earned her bachelor's degree in business administration with a major in accounting. She began her career as a certified public accountant with Deloitte, Haskins & Sells in Omaha. Duren resides in Omaha with her husband Drew Collier and their four sons.
