CP+B's global chief executive Lori Senecal is to leave the MDC Partners agency at the end of the year.
The MDC agency confirmed Senecal's departure in an all-staff email last night, according to an agency source. The news was first reported by AdAge.
Senecal has been chief executive of Crispin Porter & Bogusky since March 2015, and held an additional role of president and chief executive of MDC's Partner Network.
Immediately prior to moving to CP+B, Senecal was executive chairman of its sister agency KBS from August 2014. She joined the latter agency in 2009 as president and chief executive, as it rebranded from Kirshenbaum Bond & Partners to Kirshenbaum Bond Senecal & Partners (now KBS).
Before moving to KBS Senecal was president of McCann New York (then McCann-Erickson, New York).
In a profile piece last year, Campaign US editor-in-chief Douglas Quenqua described Senecal as a "complicated character who doesn’t fit the mold of your typical back-slapping CEO."
Senecal's departure, which includes her exit from the ad industry altogether, had been planned since her arrival at the agency in 2015, according to AdAge.
