Rosemary Stevens was born and raised in "the Jerz" (New Jersey). The daughter of a trucker and an Irish Catholic, Rosemary grew up with mixed sensibilities about society, and how to interact with other people. At the age of five, Rosemary's older brothers introduced her to the world of comedy via late night television, and a wannabe was born. Rosemary got the hell out of "Jerz" and attended New York University where she focused in Humanities and Majored in Dramatic Literature, History of Theater and Cinema Studies. Rosie also went to school in Dublin, Ireland, where she studied her ancestry and language through Trinity College Dublin. After breaking a few hearts, she returned to NYU, and was a Theater Associate for the Irish Arts Center.

To make ends meet, Rosemary pursued the wonderful world of temping (office detention for grown ups). Jay and friends took pity on Rosemary when they found her asleep at a bar—the poor thing. They pooled together $300 for Rosemary to take her first improv class with Armando Diaz. Corrine soon befriended Rosemary when she was invited to play with the improv group Crazy Bitches. They then co-hosted Royal Wood Comedy Night in Williamsburg Brooklyn with their friend Rachael Mason.

Today, Rosemary is a writer, actor, improviser, and stand-up comedian. She has performed at various venues throughout New York City, including Gotham Comedy Club, New York Comedy Club, the Magnet Theater, and well, lots and lots of bars. She can be found at the Magnet Theater, either on stage performing with her resident ensemble "El Partido" or in the office having a mild aneurism. Rosemary enjoys boozing it up, mocking Europeans, kitten pictures, glam rock videos, vacuum attachments, and what else?… oh yeah, making people laugh.
