Cody Sullivan was trained in improvisation at the iO Theater in 2015. He performed on house teams from 2016-2019.

While in Chicago he workshopped his solo performances. He wrote and performed sketches for shows primarily at the iO and The Annoyance Theater, eventually creating two solo shows from this amassed material.

In 2019 he moved to Provincetown. During pandemic he began exploring solo improvisation and solo staged theater, playing all the characters engaging in dialogue with himself.

In the summer of 2023, he started CODY PLAYS at the Gifford House. His godmother Saltine has mostly retired to Eggs Isle, but occasionally comes back to the mainland for a show.
