With nearly sixty roles to his credit, baritone Jason Detwiler has become well-known for his magnetic and energizing stage performances. His voice and acting have been described as "emotionally fervid", "richly expressive" and "commanding", embodying characters ranging from the comedic Gianni Schicchi to the dramatic Renato  (Un ballo in maschera). Among his most widely acclaimed roles are Eugene Onegin, Il conte di Luna  (Il trovatore), Zurga (Les pêcheurs de perles), and Nick Carraway (The Great Gatsby). ​ His most recent engagements include a debut of Ugo in Jake Landau's Pietà with the Narnia Vocal Arts Festival at the Teatro Comunale di Narni in Italy, reprising the villanous Il conte di Luna with Opera in the Fields, Marcello (La bohème) with Light Opera New Jersey, Count Almaviva (Le nozze di Figaro) with Gemma Arts.
