A native of Manhattan, Lisa Loomer studied theatre at Brandeis University and New York University's Tisch School of the Arts. She soon began performing off-Broadway as an actress and working with a political comedy group at the West Bank Cafe. Tired of performing other people's monologues, Loomer began writing her own material under the pseudonym Jane da Vinci. Her first work for the theatre was the collaboration titled A Crowd of Two, which was produced at New York's American Place Theatre. Her one-woman show All by Herselves was performed at the Westside Arts Theatre, New York. In 1985 she served as writer in residence at INTAR in New York. She was a contributor to A . . . My Name is Still Alice, which premiered at Second Stage in New York City and has played at numerous locations around the country.
Due to the critical and popular success of The Waiting Room, Loomer has been besieged with offers to write sitcoms, screenplays, and articles on health and beauty. She has hopes of writing a Latino sitcom and has made two attempts: "Gloria," about a Puerto Rican talk show host, and "East L.A.," set in an unemployment office. Her film Looking for Angels was developed by Sundance in Cuba, where she worked with Gabriel Garcia-Marquez. She adapted Susanna Kaysen's memoir of her two years in a mental institution, Girl Interrupted, for Columbia Pictures and is writing a screenplay for Winona Ryder and Fox 2000 based on Dreaming. Her recent play Maria! Maria, Maria, Maria was commissioned by the Mark Taper Forum in Los Angeles.
Loomer is an alumnus of the New Dramatists. She currently resides with her husband in Sherman Oaks, California.
