Oak Tree National

Oak Tree National opened on May 1, 1976 as Oak Tree Golf Club, the first major commission for architect Pete Dye under a bold directive from developers Ernie Vossler and Joe Walser Jr.: build the hardest golf course in the world. The result carried a USGA rating of 76.9 against a par of 71 -- the highest course rating in the country at the time -- and was named to Golf Digest's 'America's 100 Greatest Courses' the following year, the youngest course ever to make that list. Dye has called it the finest inland course he ever built, a distinction he draws even against his own seaside designs at Harbour Town, Casa de Campo, TPC Sawgrass, and Long Cove.

The course's championship-hosting record is sustained and real, not a single legacy moment: the 1988 PGA Championship (won by Jeff Sluman), the 2006 Senior PGA Championship, the 2014 U.S. Senior Open, and an announced return for the 2027 Senior PGA Championship. Each of these was independently re-verified against Wikipedia, PGA.com-linked sourcing, and Edmond's own tourism site during this research, precisely the kind of second-pass verification the platform's research discipline calls for on a nationally significant, frequently-cited venue. The club is now sole-owned by Everett Dobson, who bought out a former majority owner and two minority partners.

What elevates Oak Tree National to a destination exception rather than simply a famous private course is the residential-relevance evidence beyond championship prestige alone: the club sits inside the 1,154-acre guard-gated Oak Tree neighborhood, where homes range from roughly $200,000 to just under $5,000,000, and directly borders The Oaks at Oak Tree, a purpose-built 74-home gated subdivision immediately adjacent to both Oak Tree courses. The neighborhood has a documented, ongoing pattern of professional golfers choosing to live there -- current PGA Tour and major-championship-caliber players including Scott Verplank, Viktor Hovland, and Kevin Tway, alongside historic 'Oak Tree Gang' members like Gil Morgan, Bob Tway, Mark Hayes, and Willie Wood -- a real golf-driven residential demand pattern distinct from, and beyond, the club's own private membership roll.

A specific fabrication-risk catch from this research: one aggregator source (1golf.eu) states the course 'opened in 2009,' a claim flatly contradicted by every other source reviewed (the club's own site, Wikipedia, and multiple historical retrospectives), all confirming the actual 1976 opening date. That 2009 figure has been treated as unreliable and excluded from this record.
