Andrew Nienaber's productions of The Barber of Seville have been called "a rousing success" by the Winston-Salem Journal, and “legitimately hilarious” by Berkshire Fine Arts, and his Elixir of Love for Resonance Works Pittsburgh, awarded the American Prize for "Best Opera Performance of the Year", was hailed as "utterly, fabulously engaging," and "…one of the most charming entertainment experiences you can have this season…"
His other directing credits include Tosca for l'Opera de Montreal, Opera Idaho, Opera Birmingham and Permian Basin Opera, Rusalka for Resonance Works Pittsburgh, The Magic Flute for Piedmont Opera and The Elixir of Love for Opera Idaho and Hubbard Hall Opera. He served as the first Artistic Director in Permian Basin Opera’s history, helping to guide the company’s artistic vision as they ventured into the business of producing opera.
As an Assistant Director he has been on the directing staff of several major opera companies around the nation, including Dallas Opera, Florida Grand Opera, Cincinnati Opera, Michigan Opera Theater, Ft. Worth Opera and Central City Opera. He was the stage director for Opera Pacific’s acclaimed Opera Camp program, including the world premiere of Das Püppet, a pastiche of Wagner and Beethoven with a story written by children, and the United States premiere of The Star Child, for which he wrote the English libretto.
