Teng-Chien was born and raised in Taiwan. He started his professional journey as a community social worker for an orphanage in Taiwan. Teng-Chien then became an accomplished English teacher which brought him to the world of Montessori. Teaching English in Montessori schools in Taipei opened his eyes to an entirely new perspective. The experience of teaching English in Montessori schools presented Teng-Chien with a sponsorship by Ms. Lam of Taipei Montessori Kindergarten. He obtained his Assistant to Infancy Diploma with Judi Orion in Denver, Colorado; and, his Primary Diploma with Joen Bettmann in Cleveland, Ohio. During Teng-Chien’s years working with children he participated in translating courses for several age levels. Teng-Chien has worked mostly in Asia, primarily Taiwan and China. He has served as an observer and consultant in Hong Kong, Thailand, and Singapore.
In 2019, Teng-Chien became an Association of Montessori International (AMI) Primary Trainer. He started his first position as a primary trainer as the Director of Training at Train Montessori by Great Work, Inc. Teng-Chien believes fervently that being a trainer facilitates other people’s transformational journey in the Montessori training courses as well as their own individual transformation.
