In addition to her native English, she speaks Swedish, German, and French—and is now working on increasing her proficiency in Spanish.

Ms. Jemsby earned BA and MA degrees in Modern and Medieval Languages at the University of Cambridge, U.K. In 2015, she became a Fellow in the Head of School Program of the Klingenstein Center at Columbia University.

Ms. Wang Pisa is a communications strategist who loves bridging the gap between big ideas and the daily collaboration it takes to bring them to life. Equally comfortable partnering with a board of trustees on strategic planning or diving into the weeds of web design, multi-channel marketing, and video editing, she enjoys operating as a versatile "Swiss Army Knife" for educational communities.  

Ms. Wang Pisa’s path to WIS has been shaped by a lifelong connection to global education. A native speaker of English and Mandarin Chinese, with some knowledge of French, Spanish, and Italian, she began her career as a bilingual elementary homeroom teacher in Taipei. After earning her MA from University College London, she spent years shaping digital storytelling and community engagement for prominent cultural and non-profit institutions in Washington, DC, including the Kennedy Center, the Smithsonian Institution, and the DC Arts and Humanities Education Collaborative.  

Deeply invested in the local DC school landscape, Ms. Wang Pisa serves as the Vice Chairman of the Board for IDEA Public Charter School and manages communications for the Janney Elementary PTA — where she loves using creative, organic content to help families and educators feel genuinely connected.

At WIS, Ms. Wang Pisa leads the marketing and communications team with a focus on shaping the school's visual identity, supporting institutional goals, and celebrating the vibrant, multilingual stories of its global community.
