Ulta Beauty announced Monday that its Board of Directors has unanimously appointed Mary Dillon as Chief Executive Officer and a member of the Board of Directors, effective July 1, 2013.

Mary, 52, comes from U.S. Cellular, a $4 billion national wireless carrier, where she served as President and Chief Executive Officer and a Director since June 2010. Prior to U.S. Cellular, Dillon served as Global Chief Marketing Officer and Executive Vice President for McDonald’s Corporation, from 2005 to 2010.

“After conducting a thorough and robust search process, the Board believes that Mary is the ideal person to lead Ulta Beauty as we enter our next phase of growth,” said Dennis Eck, Interim Chief Executive Officer of Ulta Beauty, in a statement. Dennis will step down from his role when Mary assumes hers at the beginning of July. “Mary brings strategic vision, a rich consumer marketing background, strong operational experience, and a passion for the customer. Her experience with developing national brands, her expertise in the digital world, and her track record in building strong teams will all be important assets for Ulta Beauty. After spending the last several months working closely with the management team, I am certain that Mary will be an excellent cultural fit for the organization and lead Ulta Beauty to the next level.”

In a statement, Mary said, “The Company is well positioned for the future and I look forward to working closely with Ulta Beauty’s excellent leadership team and 16,000 dedicated associates to build on its proven growth strategies.”

Prior to McDonald’s, Mary was an executive at PepsiCo, where she held various positions of increasing responsibility, including President of the Quaker Foods division. Additionally, she served as a member of the Board of Directors for Target Corporation since 2007, and served as Chair and Executive Committee member for CTIA – The Wireless Association. Dillon received a bachelor of science in Marketing and Asian Studies from the University of Illinois at Chicago.

Ulta Beauty’s CEO spot was left vacant in mid-February when Chuck Rubin left the company for the CEO position at arts and crafts retailer, Michaels.
