Margaret McCarthy's stage plays use  the heightened language of her poetry as their basis. As a working photographer she brings a strong visual sense to telling stories on stage; in her plays she hopes to meld the pleasures of the eye and the ear.

The Sacrificial King: A Play for John Lennon  was given a New York City showcase production by The World 3 Theatre Company, preceeded by staged readings at The English Speaking Union in New York City and at Duke University, N.C.  Young theater artists of Duxbury High School chose this script (of any) to perform as their entry to The Boston Globe sponsored Massachusetts High School Drama Guild (MHSDG) Festival. Their production at John Hancock Theatre, Boston, took festival awards. 

Her stage play, Deirdre Retrograde uses her own cycle of poems to give voice to the heroine of Irish myth. It resulted from McCarthy’s ongoing involvement with the literature of women in myth, which has been a continual source of inspiration for her creative work. The play was read at La Mama Theatre, NYC, as part of its Experiments Reading Series, and later staged as part of Dreamcatcher Entertainment's Talent On Tap Reading Series.

Her poetic monologues have been performed at Irish American Writers and Artists (IAW&A) monthly salons, and programs at Poetic Theatre, NYC, The English Speaking Union of New York and The Hudson Valley Writers Association.

She is a member of The Dramatists Guild of America, The Authors Guild and PEN USA.

Her poetry collection NOTEBOOKS FROM MYSTERY SCHOOL (Finishing Line Press, 2015) was a finalist for The New Women's Voives Award. McCarthy's poetry and poetic monologues have appeared in numerous literary magazines, journals and anthologies including: The Pagan Muse:Poems of Ritual and Inspiration,  Working Papers in Irish Studies, Gargoyle Magazine, Shaking Like A Mountain: On line Literature about Contemporary Music, Poetry New Zealand,  California State Poetry Society Quarterly, to name a few. McCarthy has also reviewed for Groundswell MagazineNew Directions for Women and The Chiron Review.

She has received fellowships as a playwright, poet and photographer form The Virginia Center for the Creative Arts, The Ragdale Foundation and The Hambidge Center.

She works as a professional photographer in New York City; her landscape photographs and images based on Celtic myth have been widely exhibited.
