Milaimys “Milly” Castellón (She/Her/Ella) is a professional actor, vocalist, and storyteller currently based in South Florida. A proud first-generation Cuban-American artist, her work is deeply rooted in culture, community, and the belief that theatre has the power to connect us all.

In 2023, Milly earned her Bachelor of Fine Arts in Music Theatre from the University of Florida / New World School of the Arts College. Since then, she has worked hard to carve a distinct path for her artistry.

In 2025, that passion led Milly to found The Open Space, a creative collective dedicated to uplifting the bold, underrepresented narratives of the Greater Miami community. This emerging organization aims to champion innovative collaboration, artistic risk-taking, and inclusivity - centering voices that have too often been pushed to the margins.

Outside of her creative life as a performer and theatre-maker, Milly finds joy in the everyday - caring for her tropical fish tank, cooking spicy meals with her partner, and planning their next big adventure. Wherever she goes, Milly is proud to share her child-like wonder, vision for radical acceptance, and commitment to disrupting the status quo in all artistic spaces.
