Susan Winslow has been promoted to CEO at Macmillan Learning, making her the first woman to lead the Holtzbrinck-owned educational publisher, the sister company of the U.S.'s fifth-largest trade publisher. Winslow had been serving as president of the company since September 2020.

In her new role, Macmillan officials said, Winslow "will oversee the company’s short and long-term global growth and continue leading the company’s digital transformation in support of all students, no matter their background or abilities."

Winslow has been with Macmillan Learning since 2007, when she was brought aboard as general manager, and has been part of the company’s senior leadership since 2015. During her time with the company, Winslow oversaw the development and launch of the company's Achieve platform, in addition to doubling the size of Macmillan Learning's AP High School business arm.

“Susan is an authentic leader who has the respect and admiration of the company’s employees, authors, and customers,” said Holtzbrinck Publishing Group’s Chief Operating Officer, Filmon Zerai. “As President, she successfully navigated the company through a rapidly-changing market at one of the most pivotal moments within the education industry, all while also launching a new digital learning platform and expanding internationally. Even with all this change, her focus remained steadfastly on supporting students and their learning.”

"We have the opportunity to do something meaningful: to change lives by helping students feel like they belong, and that they deserve to be in the classroom; to help them achieve their goals," Winslow said in a statement. "My north star for Macmillan Learning is to continue producing technology and course materials that fully engage students, providing them a doorway to what’s possible."

"There are few things more powerful than an education," Stefan von Holtzbrinck, CEO of Macmillan parent company Holtzbrinck Publishing Group, said in a statement. "Susan deeply understands this and has made it her mission to lead Macmillan Learning to enable this opportunity for all students."
