Most of Mimi's acting career happened in Boston between 1986 and 1999. During that time, her primary stage work was with the Wheelock Family Theatre, an Equity house that pioneered multicultural casting, and the award winning Beau Jest Moving Theatre with whom she devised and performed several original productions, including an adaptation of the comic strip Krazy Kat. Mimi also toured schools with Theatre Espresso, and co-wrote a piece on Japanese Internment Camps called Justice At War.

In Seattle, she occasionally gets up on stage for a reading or small productions. Most recently, she was in The Realm of Whispering Ghosts at the Bath House, directed by Arny Zaslove.
