A look from the new Ryan Seacrest sportswear addition.

Kelly Mullens Brown, a key executive at Ryan Seacrest Enterprises, is leaving her post as president at the end of February.

Brown, who has been with the company for more than seven years, oversees corporate strategy, brand innovation and strategic alliances for Seacrest, and his various business and philanthropic interests.

She was instrumental in the creation of Seacrest’s apparel collection, Ryan Seacrest Distinction, at Macy’s in 2014. Brown joined the company as executive vice president of external relations in July 2012, and was elevated to president in November 2013. She also holds the title of president of RSD Lifestyle LLC, a role she took on in July 2016.

“I’m grateful to Kelly for her significant contributions and unwavering dedication to my business and philanthropic interests over the past seven years,” Seacrest said. “I’ve thoroughly enjoyed working closely with and mentoring Kelly. Her intelligence, curiosity, passion, creativity and spirited drive will ensure she is successful in whatever path she chooses going forward.”

He said Brown has “a strong track record in cultivating strategic and successful partnerships, negotiating and executing complex, new business initiatives with a commitment to quality in everything she does,” he added.

Brown said her duties will be split among the company’s executive team.

“I’m indebted to Ryan and appreciate the faith and confidence he gave me throughout my tenure. I’m proud of everything we accomplished together,” Brown said. “This job has been one of the highlights of my career. While I’ve loved every moment, and learned a tremendous amount during this journey, I’m excited and ready to tackle new challenges.”

She is expected to become more involved in mentoring female entrepreneurs. She serves as a board member of Beautycon, and is a board advisor to Parachute, Girlboss Media and The Goods Mart.
