Gravity Group, LLC was founded in 2002 by the top talent from CCI. Lawrence Bill, Chad Miller, Korey Kiepert and Michael Graham have worked on over 40 coaster projects between them, and have a wealth of expertise which has allowed them to storm into the wooden coaster market.

Intitially, Gravity Group consulted on existing projects, while getting ready for their first actual coaster build. So far, their five coasters - including Hades at Mt. Olympus, The Voyage at Holiday world and The Ravine Flyer II at Waldameer - have massively impressed both public, enthusiasts and park owners alike. The Voyage thrills with a mix of high drops, tight 90 degree angled corners and multiple tunnels. It features a massive 24 seconds of airtime and was one of the most exciting coaster projects of 2006.
