Event History

In 1983, Paul Greening, local community member, chaired the “First Annual Marklund Home Invitational Golf Tournament” held at Itasca County Club.  There were 42 golfers and the event broke even.  In 1984, the event was co-sponsored by the Addison Kiwanis Club, and was officially renamed the “Stan Haverkampf Memorial Golf Outing,” named after our co-founder who passed away in 1977.  NFL Hall-of-Famer Gale Sayers began hosting the golf outing in 1988, and in 1990 Marklund founder Claire Haverkampf agreed to rename the event “The Gale Sayers-Marklund Golf Tournament.”  White Sox legend Minnie Minoso was in attendance.  Since then, many former professional athletes have supported the Marklund golf outing including Bob Love of the Chicago Bulls, Dan Hampton, Emery Moorehead and Bob Avellini of the Chicago Bears, Billy Williams, Randy Hundley and Rich Nye of the Chicago Cubs, Stan Mikita of the Chicago Blackhawks, and Jack Perconte and Eric Soderholm of the Chicago White Sox, to name a few.
In 2017, the 35th Annual Marklund Golf Classic moved to a new venue, the renowned Cog Hill Golf Club in Lemont, IL, where golfers had the opportunity to play on Course 1 and the championship Dubsdread Course for the Porter Cup trophy and title.
In 2025, we found a new home to host our 43rd Annual Marklund Golf Eventure—the exclusive and private White Eagle Golf Club in Naperville, IL.  With 27 holes, a full clubhouse and space all to ourselves, Marklund is thrilled to take this outing to a new level and build on the existing excitement of an already robust and successful day. With a capacity for 220 golfers, and another 80 for Evening Access, Marklund is excited to unveil a day of great golf, and an evening of EVENTURE for everyone who participates.
