Meet the CEO of Veritiv, Mary Laschinger. She joins the prestigious Fortune 500 as the newest female CEO—one of 21 women on the 500.

The Atlanta-based paper and publishing company debuted on the Fortune 500 for the first time at number 323. The company was created in 2014 after a spinoff from International Paper and a merger with Xpedx and Unisource Worldwide. The combination had 2015 revenues of $8.7 billion.

Laschinger talks with Fortune’s Susie Gharib about the leadership challenges of building the company and creating a cohesive culture based on shared values. She named the company “Veritiv” by combining the word “active” with the Greek word for truth: “veritas.” She says, “We need people to do what they say they will do in order for us to be successful and to be honest with our customers.”

Laschinger grew up on a dairy farm in rural Wisconsin, with four brothers and three sisters. She didn’t go to college until she was 21 because she lacked “self-confidence” and was only a “B-average student.” But things changed for the better for Laschinger after graduating from the University of Wisconsin, earning an MBA from the University of Connecticut, and getting her first job at Kimberly Clark. She shares her leadership lessons and her advice to young women on what it takes to be a successful leader.
