As President of Games for Change (G4C), Susanna leads the organization best known for the annual Games for Change Festival, dubbed by national media as “the Sundance of video games.” Under Susanna's leadership, G4C has significantly expanded its programs and impact—including G4C Learn, a portfolio of education initiatives that empower the next generation of game-changers to drive real-world impact through games. The G4C Student Challenge, the flagship learning program that she developed with the NYC Department of Education in 2013, has grown to reach 10,000 students each year across seven partner cities. In 2017, she launched the XR for Change initiative to build a community of practice around radical new ways to improve lives using emerging immersive technologies.

Susanna has initiated dozens of other G4C programs in partnership with clients like American Express, Verizon, AARP, United Nations, Epic Games, Carnegie Foundation, Autodesk, and Ad Council. As an Executive Producer, she spearheads G4C's impact media projects, connecting award-winning creators with mission-oriented organizations. Prior to Games for Change, Susanna worked across the commercial and public sectors, including a 14-year stint in various SVP positions at BBC Worldwide.
