Tierco had no intention of entering the amusement park business. Company officials described Frontier City as "beat up" and "run down"; they planned to demolish it, subdivide the land and build a shopping center. However, given an oil bust in Oklahoma, developers lost interest in converting the park into a shopping center. In 1984, Tierco hired Gary Story as general manager of Frontier City and invested about $13 million into improving the park. As the new head of Frontier City, he quadrupled the park's attendance and revenues. Under his leadership, two rides, a ticket booth, sales office, and a petting zoo were added to the park. Food service improved. In 1988, Tierco shifted its strategic direction to amusement parks. It sold much of its property in the late 1980s, generating capital to reinvest in Frontier City. As this reinvestment paid off, more capital became available, creating further growth. By 1991, Tierco opened White Water waterpark in Oklahoma City (the name later became Six Flags Hurricane Harbor Oklahoma City). The company realized the key to boosting a park's attendance was to add new and exciting rides and make it family-friendly. Tierco acquired the financially troubled Wild World in Largo, Maryland, in 1992 and later changed that park's name to Adventure World. With a $500,000 investment, Tierco expanded Wild World's kiddie section and remodeled its buildings to give the park a tropical look and feel. Story was promoted to executive vice president after the purchase of Wild World. In 1994, he was promoted again to president and chief operating officer (COO). More flat rides and two roller coasters were added to that park. Since Tierco was on its way to becoming a "premier" regional theme park operator, in 1994 it changed its name to Premier Parks, Inc. Kieran E. Burke, chairman and chief executive officer (CEO), noted that the new name signified the beginning of a new era for the company. In the second half of the 1990s, Premier picked up speed. In 1995, the company acquired these Funtime, Inc. properties: Geauga Lake near Cleveland, Ohio, Wyandot Lake in Powell, Ohio and Darien Lake near Buffalo, New York. In 1996, Premier added to its portfolio, buying Elitch Gardens in Denver, Colorado, the Waterworld USA waterparks in Sacramento and Concord, California, Riverside Park in Agawam, Massachusetts, and Great Escape and Splashwater Kingdom in Queensbury, New York.
