Before Ruben Toral arrived in 2001 as Bumrungrad International's marketing director, "we were a Thai hospital serving a Thai community," he says. "Now we're an international hospital that just happens to be in Thailand." Overseas patients have more than doubled on his watch, generating the majority of the privately owned hospital's revenue.
