After she finished Graduate School of Education at the University of Pennsylvania, she became a Chinese project coordinator/instructor at the Lauder Institute of the Wharton School, and a Chinese Lecturer at the Department of East Asian Languages and Civilization at UPenn. She also taught at Princeton University and its Princeton in Beijing summer program as a Chinese lecturer during her early teaching years. Throughout her career in higher education, she offered various Chinese courses to college students, ranging from beginning, intermediate to advanced Chinese, as well as specialty courses such as business Chinese and Chinese writing courses. After she became a mother, her passion in teaching Chinese as a foreign language extended from teaching college students to young children.  In 2012, she joined Chinese American International School in San Francisco as an elementary school teacher and worked with children from first grade to third grade. In becoming a mother of three, children inspired her to expand and advance her qualifications in early childhood education as a program director. This pursuit eventually led her to co-found Marco Polo Children’s School and take on the role to build and oversee its Chinese immersion program once the school is in operation. 

She fell in love with Reggio Emilia philosophy during her studies in Early Childhood Education and extensive tours for her own children’s preschools. She finds Reggio Emilia philosophy the most holistic approach to a child’s overall development.  Her belief is that, by honoring children’s innate curiosity and ability to construct knowledge with teachers, children are fostered to be life-long, active learners. With this belief, she is dedicated to integrating the beautiful concept of Reggio Emilia approach with Chinese immersion curriculum. Besides chasing her children around the house to play with them, Josie enjoys keeping an active and healthy lifestyle by making healthy meals and exercising. 

Jack Hwang, Co-Founder    

Born in Taiwan but grew up in LA, Jack has truly embraced the spirit of exploration in today’s global environment.  After spending his formative years in Arcadia, Jack ventured to the East Coast and attended the Johns Hopkins University, majoring in International Relations with a Minor in Economics, followed by an MBA from the Wharton School, and an MA in International Studies from the University of Pennsylvania.  In between, he spent a year as an exchange student at the Waseda University in Tokyo, Japan; he has worked and lived in Los Angeles, Beijing, Shanghai, Guangzhou, Hong Kong, Kaohsiung and Taipei.  As such, if you are speaking a language other than English - such as Mandarin, Japanese, Spanish, or dialects such as Taiwanese or Cantonese - he might just be able to join your conversation!

In his early career, Jack worked primarily in the financial services industry for companies such as Andersen and AIG.  However, the education industry has always been in his DNA, as his parents own and run reputable preschools and elementary schools in China.  At the end of 2007, Jack joined his family and has played an integral part in growing the various schools, as well as expanding the school’s outreach into international programs in the US, Canada, and Australia.  Being part of a language and cultural immersion initiative is nothing new to Jack, as he has personally participated and organized such programs over and over again.  In 2016, seeing that more and more parents are embracing the importance of cultural diversity and language learning, Jack set in motion the plan to bring Marco Polo Children’s School to the Irvine community.  

For Jack, things have come full circle coming back to California, as the major drivers for Marco Polo were to build a school that his 3 toddler boys can enjoy, and a chance to make a positive contribution back to the Southern California community where he grew up. During his spare time, Jack loves to play a game of tennis or shoot some hoops, as he used to play competitively in both sports.  You might also find him with his kids and friends at baseball stadiums (Go Dodgers!) and beaches.
