Jack broke the global taboo of toilet and sanitation by bringing it to global media centre-stage with his unique mix of humour and serious facts since 2001.

After attaining financial independence at age of 40 as a businessman, he decided to devote the rest of his life to social work.
He established the Restroom Association of Singapore (RAS) in 1998, which addresses the state of dirty public toilets in designs, building codes and poorly trained cleaners. Realising the need for a global body on the subject, Jack created the World Toilet Organization (WTO) in 2001 as a global network and service platform for toilet associations, academia, government, UN agencies and toilet stakeholders to learn from one another and leverage media and corporate support that in turn influenced governments to promote sound sanitation and public health policies. The World Toilet Summit series has been hosted in Singapore, Seoul (Korea), Taipei (Taiwan China), Beijing (China), Belfast (UK), Moscow (Russia), New Delhi (India), Macau (China), Shanghai (China) Bangkok (Thailand), Philadelphia (USA), Hainan (China), Durban (South Africa), Solo (Indonesia) and
