As the Vice President of Twitter LATAM and Canada, Melissa leads Twitter’s teams across the region focused on expanding advertising revenue, driving innovation, and building Twitter’s brand.

Melissa joined Twitter in 2012 when it began building out its Revenue team, and she has held multiple roles as the company has grown. Most recently she was the Head of Global Brands, running the team that oversees Twitter’s global advertising partnerships, or key accounts. Prior to this role, Melissa led Global Brand Advocacy at Twitter, which focused on market development, building relationships with C-level executives, and education at scale across brands. 

Before joining Twitter, Melissa spent 11 years in the agency business, with her last role as senior vice president at Fleishman-Hillard, leading its New York consumer digital team, where she was a trailblazer in managing the shift into digital, social, and mobile. Working with the global agency’s largest clients, her team pioneered programs that went beyond campaigns — they also fundamentally changed how these brands worked within these new channels, developing long-term business strategy, content and community management models, and managing crises.

She sits on the boards for She Runs It and the American Advertising Foundation. She was inducted into the AAF Hall of Achievement in 2019. 

Melissa graduated from the University of Missouri-Columbia School of Journalism. She is @melissabarnes on Twitter.
