Wunderman Health chief executive Becky Chidester told MM&M that Wunderman Health will continue to report to parent company Wunderman, but will collaborate closely with the new group. "Health and wellness is one of the most exciting sectors of the global economy and offers enormous opportunities for our businesses," said Sir Martin Sorrell, chief executive of WPP. "This new unit is significant because it represents the next evolution of horizontality, through which WPP will continue to lead and transform health marketing."
