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".

Since moving to Boise Idaho in 2007 she has performed nearly a dozen roles with Opera Idaho. Roles include Siebel (Faust), Tisbe (La cenerentola), Suzuki in Madama Butterfly, Augusta (The Ballad of Baby Doe), Mother (Hansel & Gretel), Dina (Trouble in Tahiti), Anna (The King and I), Maddalena (Rigoletto), and most recently Third Lady (Die Zauberflöte).

Last season’s engagements included soloist in Berlioz’s Romeo and Juliette with the Boise Philharmonic, Mahler’s Das Knaben Wunderhorn with the Boise Wind Quintet, and a return to Livermore Valley Opera to reprise her role as Suzuki.

Mahler's Second Symphony and Picnic at the Pops: music of Gerschwin. In the current season, she has sung with the Boise Baroque and Boise Philharmonic in Bach's Magnificat and Beethoven's Ninth Symphony. This spring marks a return to Stockton Opera in the role of Cherubino (Le nozze di Figaro).

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, Rosina (Il barbiere di Siviglia), 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, Florida Symphony Orchestra, 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 and Second Symphony, Herzogenberg’s Die Geburt Christi, and Einhorn’s Voices of Light.
