OUR TEAM

Hai-Anh Vu - Founder & Director

Hai-Anh Vu grew up in Hanoi, Vietnam, and received her Bachelor of Arts from Bowdoin College (Brunswick, ME), where she majored in Economics and French and minored in Gender Studies. A marketer by profession, she has lived, studied, and worked in Hanoi, Ho Chi Minh City, New York City, Washington D.C., Toulouse, and Hong Kong, before landing on Whidbey Island in 2020 where she now lives with her husband and two school-age children on a farm in Greenbank.

A liberal arts college graduate and an avid educator at heart, Hai-Anh deeply believes in giving children a well-rounded education with global perspectives. Inspired by the many enrichment programs for children she saw in big cities, she wants to create similar opportunities for children like hers in Whidbey through Whidbey Island Language, Art & STEM Center. Hai-Anh now oversees all aspects of WILASC, though her most favorite parts are meeting parents and students and creating new class offerings.

Keegan Harshman, Music Instructor

Keegan Harshman grew up on Whidbey Island participating in the music programs of Chris Harshman (his father and South Whidbey High School’s band director). As a young child, Keegan was encouraged and supported to pursue any musical direction that caught his interest, which is something he plans to pass on to his son, Jazper (currently a WIWS student). Keegan began playing instruments in kindergarten and played several different ones before settling on the bass. He was part of the South Whidbey High School Jazz Band—participating there in exclusive festivals. After high school, Keegan moved to San Luis Obispo, California to attend Cuesta College’s Music and Audio Technology programs, and has gone on to perform and tour with many bands and groups locally and internationally.

Keegan moved back to Whidbey Island in 2016, and is now wearing many hats in the local community: a musician and music teacher/tutor, the owner of Blue Sound music store, and the organizer of Little Big Fest – a grassroot summer music festival on Whidbey Island.
