Journalism is a noble calling and the credibility of the profession is at stake. Today, there is weaponization of information and it is dividing us. Ann Curry passionately shares how people are yearning for journalism they can trust. Her Talk powerfully explains that truth leads to trust, which leads to understanding, understanding leads to humanity and humanity can unite us all. A world-renowned journalist and television personality, Ann graduated from the University of Oregon’s School of Journalism, started her career in Ashland (and then Portland!), then quickly rose to global prominence. Most recognized for her high-profile interviews, as well as in-depth coverage of natural disasters and human suffering in active war zones, Ann’s reporting is testament to the power of journalism and its ability to connect us all.
