Lauren Decker is celebrated for her "booming contralto with amber low notes" and a "dark, chocolatey sound with a plushness of tone and amplitude of voice rarely heard in a young singer" (Parterre Box).

In the 2025/26 season, Decker returns to Deutsche Oper Berlin as Erda, 1st Norm, and Schwertleite in Wagner's Ring Cycle under Sir Donald Runnicles and La Zia Principessa and Zita in Puccini's Il Trittico under Giulio Cilona.  In the US, she appears at the Lyric Opera of Chicago as Mamma Lucia in Cavalleria Rusticana under Enrique Mazzola and sings Handel's Messiah with the South Dakota Symphony Orchestra under Delta David Gier.

Last season included performances with Palm Beach Opera (Roméo et Juliette), Teatro Nacional de São Carlos (Mahler's Symphony No. 8), and Indianapolis Symphony Orchestra (Beethoven's Symphony No. 9).  She also performed with Camerata Chicago, singing Messiah and Mozart's Requiem.

Other notable credits include roles at Toledo Opera, Madison Opera, Palm Beach Opera, Dayton Opera, Opera Philadelphia, and the Aspen Music Festival, where she was a Renée Fleming Artist.

A gifted concert soloist, Decker has appeared with the Royal Philharmonic Orchestra, San Francisco Symphony, Grant Park Music Festival, Banatul State Philharmonic, and many others in works by Mahler, Beethoven, Verdi, Brahms, and Holst.

A graduate of the Ryan Opera Center, she made her Lyric Opera of Chicago debut in Die Zauberflöte and went on to sing in Die Walküre, Dead Man Walking, Il trovatore, and La traviata, among others.

Decker was a 2019 Operalia quarterfinalist, an national semifinalist in the Metropolitan Opera National Council Auditions, and a recipient of the Richard F. Gold Career Grant.  She has trained with the Britten-Pears Programme, Dolora Zajick's Institute, American Wagner Project, and Georg Solti Accademia.
