John Gerzema

John Gerzema is the CEO of The Harris Poll, one of the most recognized names in American public opinion and market research. A four-time author and New York Times bestseller, he built a career turning consumer data into early warnings about cultural change, from the post-2008 values shift to the case for traditionally feminine leadership traits. He spent decades inside ad agencies like Fallon and Young & Rubicam before taking the helm of Harris in 2017, where he now turns weekly polling into a running read on the American mood.
