​Ms. Detwiler has sung over thirty roles with regional companies on the West Coast, favoring Mahler, Strauss, Bel Canto and French repertoire. Critics have described her instrument as "amber-voiced," "a velvety mezzo soprano voice with excellent range," with performances being cited as "riveting" and holding "center stage commandingly."
 
Since moving to Boise Idaho in 2007 she has performed nearly a dozen characters with Opera Idaho, most recently as Jade Boucher in Dead Man Walking. Last season, she reprised Cherubino (Le nozze di Figaro) with Gemma Arts, and returned to the Narnia Festival in Italy leading the Emerging Artist Program. Upcoming events include the roles Flora/ Annina (La traviata) with MidAtlantic Opera and her debut with Mississippi Opera as Orlofsky.

In addition, the mezzo has sung with Sacramento Opera, MidAtlantic Opera, West Bay Opera, San Francisco Lyric Opera, Mission City Opera, the Boise Philharmonic and Master Chorale, Northwest Florida Symphony Orchestra, Auburn Symphony, Boise Baroque and Symphony Silicon Valley as well as guest and resident artist with Opera San Jose (2002-2007).
