Tom is speaking at PricewaterhouseCoopers' annual partners meeting in Campinas, Brazil. PwC Brazil is an independently owned entity that does business under the global PwC banner. While steaming from London to Argentina in 1915, a pair of PwC professionals stopped at Rio—and, with headquarters' permission, decided to open a Brazilian office. The firm offers a wide variety of business-service products in addition to audit.
Tom guesses that this is about his 25th trip to Brazil; he began his visits in the early days of the global seminar superstars at HSM, headquartered in São Paulo.
[Addendum 22 Aug: Speaking to PwC naturally got Tom onto the subject of Professional Service Firms. Hence, this PDF: Great PSFs.]
