Clara Barton Green was born in Coronado, California, and grew up in Florida and Virginia. As a child and teenager she devoted herself to athletic pursuits, including soccer, softball/baseball, track, tennis and horseback riding, earning herself three varsity letters in high school. Clara also participated in many stage productions and was an active member of her church junior and senior-level choirs, giving her a firm grounding in sacred music.

She attended both Mount Holyoke College and Sweet Briar College, graduating from the latter with a B.A. in Music and English and earning a mention in "Who's Who Among American Colleges and Universities." She also performed in several stage productions (both straight and musical theater), as well as singing the soprano soli in such classical music productions as "The Blessed Damozel" and "Judas Maccabeus," and performing her own solo recital.

After graduation Clara worked at several regional theaters, including The Lost Colony in North Carolina and the Source Theater and Studio Theatre Secondstage in Washington, DC, where she appeared in Hair (with Tracie Thoms of the movie Rent and Ryan Duncan of Altar Boyz). Hair went on to win several Helen Hayes Awards, including Best Resident Musical. She also began directing and producing, and helmed acclaimed productions of Agnes of God and Vanities. Clara also took the opportunity to travel for nine months in the Western Mediterranean, visiting Spain, Morocco and Portugal.

In 2000 Clara fulfilled a long-standing dream and moved up to New York City. Since moving here she has worked with Mark Hollman (composer of Urinetown) and Tony-Award winner Hinton Battle. Most recently she has been seen in such roles as Viola in Twelfth Night, Puck in A Midsummer Night's Dream, Rosalind in As You Like It, Heather in the independent film The Promise, various roles including Miranda, Titania and Ophelia in the acclaimed showcase An Evening with Shakespeare's Women, and the lead role of Miranda in Dik and Jayne Are Not the Same and her award-winning turn as Calliope in Eternity: Time Without End. In addition Clara has directed A Christmas Carol, Admit Impediments, Sleeping in Tomorrow and the one-acts "A Hillside in Hell," "The Sound of One Hand Typing," "Candy, Flowers and a Card," and "Three Questions," which won the Samuel French Off-Off Broadway Festival.
