In prior seasons, notable debuts include Rosina in Il barbiere di Siviglia with Houston Grand Opera, for which Sofia was praised by Opera News for her “honey-rich sound,” “silvery top end,” and “amazingly clear passagework,” Mercédes in Carmen with the Atlanta Opera, and the Stewardess in Jonathan Dove’s Flight with Des Moines Metro Opera. Sofia has appeared with Opera Theatre of Saint Louis as Frau Grubach in the American Premiere of Philip Glass’ The Trial and Mère Jeanne in Dialogues of the Carmelites.  Other repertoire includes William Bolcom’s A Wedding, Despina in Così fan tutte under the baton of Jane Glover, and Lazuli in Chabrier’s L’étoile. Equally at home on the concert stage, she has performed Dominick Argento’s Casa Guidi (Lexington Philharmonic), Storgé in Handel’s Jephtha (Ars Lyrica Houston), Handel’s Messiah (Minnesota Orchestra), Mozart’s Requiem (Sarasota Orchestra and North Carolina Symphony), and the mezzo soloist in Falla's The Three-Cornered Hat and Schumann’s The Pilgrimage of the Rose, both with the Houston Symphony.

A graduate of the famed Houston Grand Opera Studio, Sofia was heard in a wide variety of roles during her time as a Studio Artist, including Suzuki in Madama Butterfly opposite Ana Maria Martinez, the Fox in Rachel Portman’s The Little Prince, the Second Wood Nymph in Rusalka, Nell Gwynn in the world premiere of Carlisle Floyd’s new opera, Prince of Players, and Eliza in the premiere of David Hanlon’s After the Storm.  

Sofia was a 2016 grant recipient from the Gerda Lissner Foundation and a 2015 recipient of a Richard F. Gold Career Grant from the Shoshanna Foundation.  In 2014, she was a National Semifinalist in the Metropolitan Opera National Council Auditions and won Third Place in the Houston Grand Opera’s prestigious Eleanor McCollum Competition.  Other honors include the Italo Tajo Memorial Award (CCM Opera Scholarship Competition), an Emerging Talent Award from the Kurt Weill Foundation’s Lotte Lenya Competition, the Emile Dieterle Scholarship (CCM), and an Artist Development Fellowship from Harvard University.
