Karolina Ong graduated from University of Indonesia in 2007 with bachelor degree in Communication. During the years working in Singapore as Investor Relations and Financial Consultants, she has involved in various Indonesian groups and communities. Believing that communication and mutual understanding are the corner stone of any good relationship, she started teaching Bahasa Indonesia to foster good understanding of Indonesian culture. For Karolina, language is the window to learn and absorb other culture. It has been enriching and fulfilling journey for her, seeing her students grow in both their Bahasa Indonesia fluency and their understanding of Indonesian culture. She is also experienced in teaching C level executive and advanced students who want to learn Indonesian for specific purposes such as business and banking.
