KNOW THE WORLD Tours was founded by Dorothy Hollingsworth and her husband Bill Nobleman after visiting the People's Republic of China on three diplomatic missions in the '80's. In 1991, KNOW THE WORLD Tours took its first physicians tour to China. Since then the company has extended its reach to all the continents and has organized tours for many professionals including physicians, dentists, veterinarians, teachers as well as military, opera, bridge and religious groups. An inbound business was established in 2000 and has been helmed by David Lu since inception. Having been in business for close to thirty years KNOW THE WORLD Tours is now introducing wine tours and wellness tours for 2018.
