He was educated at Holy Cross High School in River Grove, and worked at Koch Foods part-time while a student. In 1984, he received a bachelor's degree in Finance and Marketing from Loyola University.
Grendys started full-time at Koch Foods in the mid-1980s, when it had just 13 employees. The owner Fred Koch was one of his father's customers, having started Koch Foods in 1973, and offered him a 50% equity share in the business.
He bought out Fred Koch in 1992. Grendys' companies now slaughter, ship and sell chicken using the Koch Foods, Antioch Farms, Preferred Foods and Rogers Royal brands. Koch slaughters over 12 million chickens and processes over 50,000,000 pounds (23,000 t) of chicken every week.
In 2011, Koch employed 14,000 people, had an annual turnover of $2.8 billion, and was one of America's five largest "fully-integrated chicken processors."
In a 2014 interview, Grendys stated that he planned to acquire more companies and that he might branch out into another protein, but that he was "not sure what that protein would be yet." Rather than running a chicken company, he sees it as "the business of converting corn and soybeans into meat protein."
His company Koch Foods has been dogged by accusations of racism and abusive working conditions.. On August 7, 2019 U.S. Immigration and Customs Enforcement raided several food processing plants in Mississippi, one of which was the Morton, MS plant of Koch Foods. Three buses were used to shuttle off workers alleged of being undocumented. 
Grendys lives "relatively modestly in the Chicago bungalow where he grew up and drives a beat-up old Cadillac."
