In Claire’s work, she has been called everything from “The Woman Who Got the Pope on Twitter” (Wired) and “Twitter’s Pontiff Recruitment Chief” (The Washington Post) to a “Force for Good” (Forbes) and “One of the Most Generous People in Social Media” (Fast Company). As CNN said in 2017, “If Twitter has a soul, it probably looks something like Claire Diaz-Ortiz.”
