[1] When she was a student at the elementary school in Lake Harriet, Minnesota, she acted in plays that she staged herself, raising money for the Red Cross in the process.
[2] Mandeville was unable to find work on Broadway during the Great Depression, so she returned to Minnesota and acted in some locally produced plays.

[2] Mandeville and her husband, Hank Booraem, created the Blue Ridge Radio Players in Hendersonville, North Carolina, in 1991.
The group primarily worked in a recording studio, but on April 23, 1992, the Players presented their first on-stage production at East Henderson High School.
They used a computer and a fax machine to "keep the business end of things going" and supplemented dialog in programs with recorded sound effects and music.
