The Martin Agency hired Karen Costello as executive creative director, tasking her with leading the agency’s Mondelez account, which includes brands such as Oreo, Chips Ahoy! and Ritz.

“Karen is one of the top creative leaders in the industry. But she is hardly one to brag. So I will for her. She’s already making a huge difference in the place,” said The Martin Agency chief creative officer Joe Alexander in a statement.

“I was drawn to Martin because of their reputation for being great people who do great work,” added Costello. “Great work is obviously important to me, but I’m a relationship person. In the end, it’s all about the people.”

Costello arrives at The Martin Agency from Deutsch L.A., where she served as executive creative director and helped grow the office from a team of 13 to over 400 while working with clients including Target, Georgia-Pacific, HTC, Expedia and Zillow. Over the years, Costello has won all sorts of industry awards and was named in Adweek’s Creative 100 list in 2016.

Costello’s arrival marks the latest in a series of leadership hires at The Martin Agency. Earlier this month, the agency welcomed back Chris Schumaker as executive vice president, managing director, growth and CMO. Last week, Michael Chapman succeeded 31-year agency veteran Earl Cox as chief strategy officer.
