Roger Seiders is a businessman and inventor. He quit his job as a high school teacher in the mid-1970s to go full-time with his company Flex Coat, which is still in business today. So it’s no surprise that he passed on an innovative attitude to his sons, YETI co-founders Roy and Ryan Seiders. But even though the entrepreneurial spirit resonates loudly, it’s Roger’s lessons on fatherhood that stand out as Roy and Ryan raise families of their own.
