International Theme Park Services

International Theme Park Services, Inc. (ITPS) is a leisure consulting and design firm based in Cincinnati, Ohio, United States. It was founded in 1983 by Dennis Speigel and advises on feasibility, master plans, design and pre-opening operations for amusement parks, water parks and other attractions worldwide.

ITPS is a design consultancy rather than a ride manufacturer: it plans parks and selects the attractions, while the ride hardware itself comes from other builders. Its best-known project is Hopi Hari in Brazil, which it designed and built using the layout of Kings Island in Ohio as a starting point.
