GateKeeper

GateKeeper was designed by the Bolliger & Mabillard Consulting Engineers Inc. organization.  The group is typically just called B&M.  Based in Monthey, Switzerland, the company was started in 1988 by Walter Bolliger and Claude Mabillard.  In 2016, they built their 100th coaster.  While seven of their first 100 coasters have been relocated, 99 of them are still operating. ( Dragon Challenge at Universal Studios Islands of Adventure was demolished in September 2017.)
