Mike Allen, managing partner and president of 180, Los Angeles, will become the agency's global CEO, succeeding Chris Mendola.
Mr. Allen will continue to oversee day-to-day management of the agency's Los Angeles office but will add responsibility for 180's global operation. Mr. Mendola, who was a co-founder of the Omnicom Group shop, moves to the role of chairman. The firm's former chairman and co-founder, Alex Melvin, died in August of cancer.
"Without a doubt, Mike is the man to take responsibility for 180's global business," Mr. Mendola said in a statement. "He opened 180 L.A. for us five years ago and has a reputation for building very strong agency-client partnerships. Over the last 25 years, he has helped to create some of the industry's most famous and effective advertising on global brands, including Apple, Nike , Nissan, Adidas, Ray-Ban and Sony."
Mr. Allen has worked on both the client and agency sides, including seven years as a marketer at Nike . In 2007 he left 180 sibling agency TBWA/Chiat/Day to join 180. Since that time the office has grown to 85 employees from four.
Group 180, which also has an Amsterdam office, employs more than 200 people across 30 countries. The client roster includes Sony, Mitsubishi Motors, Adidas, Asics, Western Union, Eli Lilly and Boost Mobile.
