At H&K, Tierney will lead accounts in the diabetes and cancer arenas. She reports direct to Shipra Singh, MD of what the agency now refers to as its healthcare and wellbeing division.
The switch to H&K is a return to the WPP fold for Tierney – prior to Red Door she worked at Cohn & Wolfe for almost three years.
Before that she spent 18 months at Ketchum.
At Red Door, Tierney worked mainly on UK programmes in disease areas including rheumatology and vaccination.
