"As Giovanni, baritone Jason Detwiler was a total stud, strutting through his role with commanding physical and vocal strength and enough seductive energy to sway a eunuch."
Opera News- Jul. 2006
"[Detwiler] illuminated the stage...trim and handsome [he] glowed as the unremorseful, irredeemable, sexual reprobate."
Inside Bay Area - Apr. 2006
"Detwiler's Don Giovanni displayed a keen acting sense and two voices, one clarion the other covered, most useful for dramatic possibilities"
Metroactive - Apr. 2006
"In the title role...the dashing baritone Jason Detwiler looked ready for anything that might be thrown his way, adept at dramatizing the Champagne Aria, the Mandolin Aria, the sugary importunings of 'La ci darem la mano' to Zerlina, even doing plausible sword fights."
