Yoon S. Choi, Ph.D., Chief Strategy Officer and Vice President California Regions

Yoon S. Choi is the Chief Strategy Officer and Vice President of the California Regions for Spark. Choi joined Spark as the Executive Director of Spark LA in 2013, turning LA into a top-performing region in terms of fundraising, large-scale corporate partnerships, and fee-for-service contracts with local school districts. In 2015, Choi was promoted to oversee Spark's San Francisco Bay Area region as well, where she expanded the program into new districts and doubled the number of corporate partners. Today, as chief Strategy Office, Choi is leading the national growth and partnership development initiatives set out in Spark's recent ten-year strategic plan, while continuing to oversee the Bay Area and Los Angeles. Prior to joining Spark, Choi was Director of Foundation Relations at Para Los Ninos, a Los Angeles nonprofit that provides educational, family support and mental health services.
