Rangsan was born and raised in India, and during college in India he became what was known as a “Hobby Cook”. He continued to cook while attending college in San Diego after moving there in the early 80’s. Following college, he decided cooking was what he enjoyed most, so he moved to Chicago and began working up the kitchen ladder at different restaurants.
In 1988, he joined Great Chef Arun Sampanthavivat as his sous chef at Arun’s Thai Restaurant in the Albany Park section of Chicago. In 1994, the Great Chefs crew showed up to tape Chef Rangsan for the Discovery Channel’s Great Chefs of America television series.
In 2001, Chef Rangsan opened his own Thai restaurant near Chicago’s airport in Elmwood, Illinois and remains there today. On a sad note, earlier this year in 2016, Chef Arun put Arun’s up for sale and wants to retire. He said that “31 years is long enough to run a restaurant”.
