Omnicom Group named Tiffany R. Warren to a new post: Chief Diversity Officer.

Previously, Warren was vice president of multicultural programs and community outreach for Arnold Worldwide, where she pushed to recruit and sustain multicultural talent. She is also the founder of ADCOLOR, a joint effort between the AAF, the Association of National Advertisers and others to promote greater diversity in advertising, marketing and media.

Omnicom President and CEO John Wren noted: "Her twin objectives of increased inclusiveness and a better environment for everyone ... are strong indicators of her ability to lead and make a difference."

Prior to joining Arnold, Ms. Warren was the manager of Diversity Programs at the 4As in New York. In that capacity, she handled all its diversity initiatives, including an internship program and multicultural scholarship funds.

She is a blogger on Ad Age's "The Big Tent" and serves on various committees that push for greater inclusiveness in the marketplace. Warren is a founding member of the Roundtable of Advertising Diversity Executives.
