Under Jason’s direction, Mango has grown to serve language learners through a variety of outlets around the world, including public libraries, universities, K-12 schools, government agencies, and corporations. Through his work, Jason aims to transform the language-learning sphere and enrich lives with language and culture through innovative product, marketing, and company strategies.
