In a partial restructuring of the communications departments of two related Interpublic shops, Joe Benarroch has been named vice president-group director of corporate affairs for the McCann Worldgroup, and Theresa Nasi has joined from Havas’ MPG to replace him as senior vice president-global communications at sister agency UM.

Nasi had been senior vice president-global network development at MPG, and has an extensive track record handling media agency communications and public relations. She previously was U.S. director of marketing communications at Omnicom’s OMD unit, and began her career in the media department of San Francisco-based Goodby, Silverstein & Partners.

Nasi reports to UM Global CEO Jacki Kelley.

Benarroch, meanwhile, will reunite with Worldgroup CEO Nick Brien, who originally brought him in to lead the communications team at Mediabrands when Brien created the Interpublic media services holding company unit.

Interpublic described Benarroch’s role as being similar to the one he played with Brien at Mediabrands, responsible for strategic communications both internally and externally for the organization.
