As George Bernard Shaw once said, I also have been creating myself for over 15 years of working in hospitality industry until today.


Starting from serving tea and coffee in Economy class cabin of an airline to working in prestige residences in the Middle East for World’s business leaders, I learned that life gets better when I put ‘action’ into my ‘passion’.  


My name is JJ , Piriyasinee Chulasuwan, the founder and trainer of First Class Service Training Academy. 


My helpful tips to get great result and customer relationship is ‘ Be honest. Empathize. Give my best shot to achieve the best goal.’  Create consistency and one day the World will recognize you even before you realize.
