Dinn Corporation, or Dinn Corp., was a wooden roller coaster manufacturer based in West Chester, Ohio, USA. They were in business from 1983 to 1992 and built 12 roller coasters, and 5 are still operating today. 3 of the 7 defunct coasters were given steel I-Box track by Rocky Mountain Construction. The other 4 defunct coasters were scrapped and not relocated.
Charles J. Dinn was the director of construction, maintenance, and engineering at Kings Island and oversaw construction of The Beast, which opened in 1979. Dinn went on to form his own company in the early 1980s. The company managed the construction of wooden roller coasters in partnership with Curtis D. Summers' company.
Construction began on Pegasus at Efteling in late 1990, but Dinn abandoned the project following disagreements with Efteling and ultimately retired in 1991. His daughter, Denise Dinn formed a new company, Custom Coasters International that year. Summers died the following year of a heart attack at the age of 62.
