Dehnert grew up in Illinois and graduated from
Illinois Wesleyan University with a degree in musical theater. She performed there as a musician before becoming a musical director, and later was put in charge of a production.
Charles Strouse, who wrote the music for
Annie, also saw the production and was impressed, which prompted him to approach Dehnert to produce his new musical,
You Never Know. The play had its world premiere at Trinity Rep in April 2005. In 2005, Dehnert became acting artistic director after
Oskar Eustis moved on to become artistic director of
The Public Theater in New York City. ==Recognition==
