Their company, Adventure Consultants, was incorporated in 1992 and quickly became a premier expedition guiding company. That year they guided six clients to the top of Everest. In October 1993, Gary Ball died of pulmonary edema, leaving Hall to run Adventure Consultants on his own. By 1996, Hall had guided thirty-nine climbers up to the top of Everest. Although the price of a guided summit attempt - US$65,000 - was considerably higher than that of other expeditions, Hall's reputation for reliability and safety attracted clients from all over the world. Rob Hall was well known in the mountaineering world as the mountain goat or the show.
