Six Flags is quietly shuffling its corporate deck, and the ripple effects have landed squarely in San Antonio. The company’s latest leadership shakeup has put two of the region’s biggest leisure magnets - Six Flags Fiesta Texas and Schlitterbahn in New Braunfels - under intense local scrutiny.
The change came into focus after the San Antonio Business Journal reported that longtime Fiesta Texas leader Jeffrey Siebert is no longer with Six Flags. Siebert, who had been with the park for nearly nine years, is out amid what the Business Journal describes as a broader leadership reshuffle sweeping through the combined company.
Before his departure, Siebert had been shifted into a regional general manager role overseeing multiple Texas properties as Six Flags moved away from the traditional single-park president setup. That consolidation followed a merger-era reorganization that centralized many park functions and overhauled local leadership structures, and industry coverage at the time highlighted how park president positions were being eliminated as part of that strategy, according to Amusement Today.
Company moves and asset sales
While management changes were unfolding, Six Flags also wrapped up a major real estate play. In early April, the company closed the sale of six U.S. parks to EPR Properties, a portfolio deal that included Schlitterbahn Galveston but specifically did not involve Schlitterbahn New Braunfels. The move is part of a strategy to trim owned assets and redirect capital. As laid out in Six Flags’ April 6 regulatory filing and press release, EPR will team up with Enchanted Parks to operate the acquired properties, and Six Flags stated the parks will keep running with season-pass benefits honored through 2026, according to Six Flags' 8-K.
What it means for Fiesta Texas and Schlitterbahn
At Fiesta Texas, the timing of the shakeup hits after a stretch of visible, on-the-ground investment. The park has poured money into projects such as a multimillion dollar overhaul of the Sangerfest Halle food hall and rolled out new attractions during Siebert’s tenure, so a leadership change naturally raises questions about how future projects will be prioritized. Local coverage of the renovation and guest-experience upgrades was detailed by KSAT.
Industry reaction and what to watch
Theme-park trade observers say centralizing power into regional roles can speed up some decision-making but also piles more responsibility onto fewer shoulders. Managers tasked with juggling several major parks and water parks at once can find themselves stretched thin, and industry coverage has warned that lighter on-site leadership may complicate maintenance schedules, guest experience and long-term capital planning, according to Theme Park Tribune.
For now, both Fiesta Texas and Schlitterbahn New Braunfels are open for the 2026 season, and company filings say guest access and season-pass perks will continue while the corporate chessboard keeps shifting. Employees, season-pass holders and coaster die-hards around San Antonio are waiting to see who Six Flags officially taps to run the region’s parks next, and how that new leadership team will steer some of the area’s most beloved attractions.
