Anna Kosiarek is an actor, improviser, trained combatant, and published poet.
If there is a story to tell, she wants to be a part of it.
Since childhood, Anna has embraced life with an unbridled curiosity and joyful spirit. Her family constantly moved while she was growing up, giving her the skill of adaptability and the gift of experiencing cultures outside of her own. This exposure to traditions, languages, people, and stories blossomed into a love of art and expression in all forms – theater, dance, improvisation, comedy, poetry, painting, and all of the mediums she has yet to explore!
Currently residing in Oakland, California, she has performed across the East Bay, with notable roles including Alicia in The Thanksgiving Play at Altarena Playhouse, Evie in In Love and Warcraft at City Lights Theater Company, and Sister James in Altarena Playhouse’s Doubt, which went on to win the San Francisco Bay Area Theatre Critics Circle award for “Best Performance in the East Bay 2024.”
She made her San Francisco Opera debut in 2025 in Dead Man Walking, and was celebrated for her roles in The Wisdom of Eve at the Altarena Playhouse and BACCHAE with Bard Theatre.
Before moving to the Bay in 2023, she performed in the Pennsylvania Renaissance Faire as an actor and stage combat fighter, then toured the country in True To Life, a Jay Frankel production. She studied acting at Carnegie Mellon University and graduated with a BFA in Theater and Performance and a minor in Creative Writing from Emerson College.
Performing and creating at night, she spends her days teaching preschool in the forests of Marin. Teaching exclusively in the great outdoors allows her to impart her own love of mother earth to the next generation – though she learns even more from the children than she could ever hope to teach.
When she isn’t on stage or teaching, she wanders the Redwood forests looking for inspiration for her paintings and poetry, picks up trash along the shores of Lake Merritt and dances at her local pole dance studio.
