Park negotiated inclusion of gender identity and expression in the Dignity For All Students Act (DASA), a safe schools bill enacted by the New York State Legislature in 2010, and the first fully transgender-inclusive legislation introduced in that body. She also served on the steering committee of the coalition that secured enactment of the Dignity in All Schools Act by the New York City Council in September 2004. In 2005, Park became the first openly transgender person chosen to be grand marshal of the New York City Pride March, the oldest and largest pride event in the United States.
