An iconic Robert Trent Jones Jr. designed course with a rich history, SentryWorld blazed the trail as Wisconsin's first destination golf course. Owned and operated by Sentry Insurance and created through the vision of its then CEO John Joanis, the inaugural round was played on June 13, 1982 and the course quickly became famous for its world-class caliber and stunning signature "Flower Hole." In 2013, Robert Trent Jones, Jr. returned to SentryWorld, and in collaboration with course architects Bruce Charlton and Jay Blasi, oversaw a major renovation to the 200-acre course, with upgrades, improvements and changes to everything from its layout, greens, grasses and bunkers to its irrigation system, water features and even the onsite sports complex, now called the Fieldhouse. Sentry Insurance is proud to have renewed its commitment to the community by investing in this renovation and making SentryWorld Wisconsin's premier parkland golf course.
