National health and wellness director, Twitter

A quick read of Mary Ann Belliveau’s résumé reveals a career steeped in healthcare marketing and communications.

At Twitter, Belliveau must bring her 20 years to bear for the platform, as it leans into its advertising model and battles reputational headwinds.

As national health and wellness director, Belliveau must work with advertisers and agencies to roll out campaigns.

Prior to joining Twitter, Belliveau worked at Google, where she was a founding member of its industry development and marketing team, a sales-driven division whose relationships included Fortune 1000 companies as well as advertising agencies.

Before that, she served at ClearGauge, a marketing consultancy, and Jobson Healthcare Information, a healthcare comms, publishing, and med-ed company.

This year, Twitter hit a hot streak, posting three consecutive profitable quarters because of its ability to connect advertisers and consumers in real time, more ad options, and better sales execution.
