Being able to benefit so greatly as a youth, they recognize the importance of a program like tSB. It only made sense that Mylinh’s next step was to join the tSBoard in April 2019 to continue the work in ensuring the legacy of tSB lives on and that all youth who participate in the program are able to tap into their most powerful and unapologetic selves.

Mylinh works as an advocate at API Chaya. In Mylinh’s free time, they are always seeking new hobbies. They currently reside in Capitol Hill with her cat, Jackson.
