Peter McGuinness wasn't always a yogurt guy. Before joining Greek yogurt brand Chobani in 2013, he had a career in ad agencies. On this episode of the podcast, he discusses making the transition to the brand side, and the fresh self-awareness that brought him. He describes working for a brand with purpose and how Chobani is grappling with the current dip in U.S. yogurt sales as more alternatives come to market.
