To prepare Olympia Fields North for the 1961 PGA Championship (won by Jerry Barber in a playoff over Don January), the club didn't hire a golf architect. Instead, superintendent Warren Bidwell relocated 32 greenside and 13 fairway bunkers and added new tees to lengthen the course by 320 yards. Forty years later, golf architect Mark Mungeam supervised extensive changes before the North hosted the 2003 U.S. Open and made more changes again before Olympia Fields North and then-newly remodeled South co-hosted the 2015 U.S. Amateur. In 2017, Olympia Fields North was the site of the KPMG Women's PGA Championship, and the course hosted the 2020 and 2023 BMW Championship. Andrew Green has since been hired to remodel the course.
