LARRY WHEELER’S SCUBA CREDENTIALS
TDI was founded in 1992 by Mitch Skaggs, Bret Gilliam and David Sipperly after a split away from International Association of Nitrox and Technical Divers (IANTD) in 1993. The agency aimed to provide training materials and education for specialized diving situations. Some courses offered by TDI include open circuit courses such as diving with Nitrox as well as Rebreather courses. They also provide training for overhead environments like caves and wrecks, mixed gas training and were one of the first diving agencies to create a comprehensive insurance plan for technical diving instructors.
In 1998, the International Training brand expanded their offerings by starting a sister organization known as Scuba Diving International (SDI) focusing on the sport side of scuba diving. In 2000, another sister organization was launched called Emergency Response Diving International (ERDI) to teach public safety diving to public safety organizations.
