NACS congratulates the eight 2023 NACS Master of Convenience award recipients who were honored at the invitation-only NACS Leadership Forum in February, where they received a certificate and pin.

“The NACS Executive Education programs I participated in not only enhanced my professional skills but also had a huge impact on my personal development,” said awardee Staci Donahue, director, capital project controls, 7-Eleven Inc. “The coursework and networking opportunities helped me gain valuable experience, skills and resources that are moving my career and organization forward in meaningful ways.”

The NACS Master of Convenience designation acknowledges the leaders from around the globe who have invested in their personal leadership development and attended three or more NACS Executive Education programs. These leaders have also invested in the growth of their organizations—and the industry as a whole—by harnessing and infusing their strengths with a world-class curriculum and a network of like-minded leaders.

“I gained insights and confidence that enable me to lead my teams more effectively as we tackle complex challenges,” said Donahue.

Here are the latest elite leaders who are shaping the future, proactively and powerfully:
