In the newly created role, Mr. Brinegar will be responsible for driving growth for the South Korea-headquartered holding company in North America, as well as supporting the three agencies that comprise Cheil's holdings in North America — The Barbarian Group, Iris Worldwide and McKinney — to serve domestic clients and contribute to Cheil's global growth, the company said in a statement.
He will continue as chairman and CEO of McKinney, a creative agency based in Durham, N.C.
"Cheil has assembled a unique network of modern agencies in the U.S. market," Mr. Brinegar said in a statement. "My new job is to help the leaders of all three agencies to efficiently partner and build out our offering in the U.S."
The promotion follows similar moves by Cheil in other regions to strengthen the holding company. Earlier this year, Cheil established the Global Network team in London with the addition of Lotta Malm-Hallqvist as global chief growth officer and Malcolm Poynton as global chief creative officer. Last month, Aaron Lau, president and CEO of Cheil Greater China, took on the additional role of president, international, overseeing the global growth activities of the network.
Mr. Brinegar joined McKinney as chairman and CEO in 2002, a decade before Cheil completed its acquisition of the creative shop as part of an effort to expand in the U.S.
