S&S – Sansei Technologies (formerly S&S Sports, S&S Power, and S&S Worldwide) is an American company known for its pneumatically powered amusement rides and roller coaster designing. Stan Checketts with his wife Sandy (Stan & Sandy) founded S&S Sports, Inc in 1994 in Logan, Utah. S&S Sports manufactured bungee jumping and trampoline equipment. Later that year, S&S began manufacturing air-powered amusement rides which is now the main stay of the company. S&S Sports was sold in 1996. In 2002, S&S began looking for opportunities to expand their business, citing acquisitions as the best method to do so. Following the bankruptcy filing of wooden roller coaster manufacturer Custom Coasters International (CCI), S&S hired founder Denise Dinn-Larrick and several other former CCI employees to start a new wooden coaster division for the company. In October 2002, S&S founded S&S Arrow, a limited liability company which purchased the assets of the bankrupt Arrow Dynamics. However, the only Arrow Dynamics coaster design S&S continues to offer is the 4th dimension coaster. In 2004, after four wooden roller coasters were built, S&S closed that division of the company. In 2006, S&S Power opened Celebration Centre, a Family Entertainment Center featuring a number of S&S rides and prototypes. The facility was later sold and is currently no longer operating. On August 25, 2006 S&S Power, Inc. announced that Stan Checketts and Gene Mulvihill, both original founding partners of S&S, had formed a group to purchase a controlling interest of S & S. The negotiations took several months. CEO Checketts was to direct the company based on the same principles upon which it was founded; "...to provide the amusement industry with thrilling, high-quality rides the entire family can enjoy." Checketts also announced that the business operations of S&S would remain under the direction of Rich Allen, who would continue in his role as Chief Operating Officer. In February 2009, Larsen MacColl Partners acquired a significant equity interest in S&S, including all shares previously owned by Checketts.
