Prior to joining the ensemble at Bühnen Bern, he performed with the Santa Fe Opera, Washington National Opera, Dallas Opera, Atlanta Opera, National Symphony Orchestra, American Bach Soloists, Madison Opera, Opera North, Pensacola Opera, Opera Las Vegas, Baltimore Concert Opera, and Mobile Opera.

His repertoire encompasses leading roles across the lyric and dramatic bass repertoire, including Figaro (Le nozze di Figaro), Lord Sidney (Il viaggio a Reims), Vodník (Rusalka), Raimondo (Lucia di Lammermoor), Basilio (Il barbiere di Siviglia), Colline (La bohème), Varlaam (Boris Godunov), and Titurel (Parsifal). In concert, he has appeared as bass soloist in Handel's Messiah, Shostakovich's Symphony No. 13 (Babi Yar), Beethoven's Symphony No. 9, Fauré's Requiem, and Monteverdi's Vespro della Beata Vergine.
