Vantage's TEFL Training Team
Effective trainers get to know their students and their needs
Chris Demetsopoullos (Lead Trainer)
Chris has some 25 years in the English Language Teaching (ELT) industry.
Originally from London, he started his teaching career with Inlingua in the mid-1990s where he taught diverse ages of Thai students. From there, he moved up to positions in corporate business training and client acquisition.
His business English assignments led to his work as a developer of customized materials for business skills courses and Thai blue-chip corporate workshops.
More recent work has been focused on leveraging traditional teaching content onto digital platforms through interactive exercises and the creation of online tests for both the eLearning and mLearning platforms.
Chris specializes in the creation of high-level English for Special Purposes (ESP) courses and one-on-one Executive Coaching for personal development programs and Leadership Coaching.
He firmly believes in the experiential learning methodology. He is professional, reliable, creative, and has effective cross-cultural communication skills. He understands how to maximize the impact on trainees through an active approach.

Kevin Cullen (Jobs Coach)
Kevin started his career teaching English and developing course materials for the Iranian Navy as part of their English training regimen. Later as an entrepreneur in Spain, he established The English Consultancy providing language corporate training and staff development programs.
He then held significant management positions in Indonesia, Singapore, and Thailand while he earned an MBA in International Business and Marketing.
After graduate school, his focus was in the financial services sector where, in Saudi Arabia, he was charged with new product development and implemented and managed strategic partner relationships for the Saudi French Bank. He was subsequently recruited for senior managerial positions in Kuwait where he established the first marketing functionality and revitalized the corporate identity for two different local banks.
In 2010, he became evangelical about computer-adaptive language testing—a passion that led to the buyout of the Cambridge-authorized Thai BULATS agency (now Vantage). He has taught numerous business English classes for many of Thailand's blue-chip companies.
He holds a BA degree in English from the University of Washington in Seattle and an MBA from the Kellogg/Wharton affiliated SASIN business school at Chulalongkorn University.
