Tiffany Warren, senior VP & chief diversity officer, is leaving Omnicom at the end of the month after a more than 10-year run for Sony Music Group. She will become SMG’s executive VP-chief diversity & inclusion officer.

Chief John Wren noted that Omnicom was the first in the industry to create a top diversity post.

He said Warren “demonstrated an unwavering passion and dedication to diversity, equity and inclusion that has underpinned our own core values.”

Under her leadership, OMC notched “notable gains in recruiting, retaining and developing a diverse workforce across the group and have accelerated our momentum in doing more to advance systemic equity,” according to Wren.

Warren headed OMC’s “open leadership team” which includes 25 diversity champions across the holding company’s agencies and network.

OMC has launched a search for a new chief diversity officer.
