Wan-Hye started teaching in Seoul, South Korea, in 1989, and alternative & complimentary therapy courses at the City Lit in London, UK from 2005 before establishing The College of Oriental Therapy in 2013.

Her scientific approach, her theoretical research in Traditional Oriental Medicine (TOM), her study and practice of medical acupuncture combined with teaching and practice in both western and eastern therapies and her successful studies for a BSc (Hons) in Biomedicine from University of London give her considerable insight into both the effectiveness and best use of various therapies and techniques, and into the delivery of training to ensure the best student outcomes. Her courses and treatments are individually designed for each session.

She combines a solid grounding in theory with substantial hands-on practical training and lots of individual supervised exercises. This enables learners to be able to put what they have learned to immediate use, but she expects extremely high standards from her learners before she is fully confident to release them to practice as professional practitioners.
