Maryn O'Brien is a versatile wardrobe specialist from southeast Michigan with a passion for music and historical fashion. Graduating in 2019 from Oakland University, she holds a Bachelor of Arts degree in Music. Her creative talents extend to costuming, where she made her mark on the Detroit Concert Choir's 2024 Connoisseurs Series production of Donizetti's The Night Bell. Acting as the Costume Designer for Opera de Metro's inaugural season, O'Brien designed and assembled costumes for David Conte's The Gift of the Magi and Mozart’s The Magic Flute.
