Sydney Zarlengo (they/them) is a disability historian, dramaturg, and actor in the world of theater, film, and tv in New York City.

They got their BA from Mount Holyoke College where they created some of the first guidelines for accessible design in performing arts curriculum for secondary and higher education, after which they gave professional trainings at arts programs around the country. As part of this work, they staged the first all-neurodivergent cast and crew production of The Curious Incident of the Dog in the Night-Time and made its subsequent documentary.

Sydney has since worked as dramaturg and historian for both new works and adaptations from The Tank to The Public, in addition to running a new accessibility program at Signature Theatre based on the access review work they’ve been doing for years.

They also make online educational content about disability, pseudoscience, history, and media literacy with over 1.3 million views across platforms and occasionally give lectures around the city.

As a performer, they are represented by RAFCO.
