Since 2000, Ms. Detwiler has sung nearly two dozen 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".

The current season finds her debuting with Opera Coeur d'Alene as Siebel (Faust), with Northwest Florida Symphony Orchestra as Rosina (Il Barbiere di Siviglia), with Stockton Opera as Ciesca in Gianni Schicchi, and with Seattle's Sunset Club for a King and I Gala. Later in the season, the mezzo returns to Opera Idaho for her first Augusta (The Ballad of Baby Doe) and to the Boise Philharmonic as soloist in Mahler's Second Symphony.

From 2001-2007, she was a Principal Artist and Guest Artist with Opera San Jose where she sang in eighteen productions ranging from lyric to dramatic repertoire. While there she garnered much praise for her portrayal of Elizabeth Proctor (The Crucible), and took on the roles of Carmen, Suzuki (Madama Butterfly), Rosina, the title role of La Cenerentola, Dorabella (Cosí fan tutte), Cherubino (Le Nozze di Figaro), Zerlina (Don Giovanni), Stephano (Romeo et Juliette), Siebel, Prince Orlofsky (Die Fledermaus), and Flora (La Traviata) among others. In addition, the mezzo has sung with Sacramento Opera, Opera Idaho, Livermoor Valley Opera, West Bay Opera, Trinity Lyric Opera, San Francisco Lyric Opera, Mission City Opera, the Boise Philharmonic,the Boise Master Chorale, Auburn Symphony, and Symphony Silicon Valley. Her concert credits include soloist in Bernstein's Candide Suite, Handel’s Messiah, Mozart’s Requiem, Saint-Säens’ Christmas Oratorio, Mahler’s Songs of a Wayfarer, Herzogenberg’s Die Geburt Christi, and Einhorn’s Voices of Light.

Currently, Ms. Detwiler resides in Boise, Idaho with her husband, baritone Jason Detwiler, and their two children.
