Music Director


Irene Moretto is a pianist, harpsichordist, and violinist who earned a M.M. in Piano Performance and M.M. in Harpsichord Performance from Temple University, where she studied with Dr. Charles Abramovic and Dr. Joyce Lindorff. She also holds a B.M. in Piano Pedagogy. Her love of vocal music led her to attend the American Institute of Music Studies in Graz, Austria, where she studied and performed opera and lieder repertoire. She also attended the Tafelmusik Baroque Summer Institute to further her exploration of Early Music.

Irene regularly works as a collaborative pianist and has played for such organizations as the Philadelphia International Music Festival, House Music Philadelphia, and Wilson Vocal Academy. She is a founding member of the new Philly-based opera collective, Alter Ego Chamber Opera. Irene maintains an active piano studio and is on the faculties of The Baldwin School and Merion Mercy Academy. When not at the keyboard, she plays violin for various celebratory events with her string trio, Abellimento Strings.


Tom Sitzler, lyric baritone, has been capturing audiences with his warm, generous voice and convincing stage presence. Growing up in Arizona, Tom was buying CD’s of pianist Glenn Gould and composer Rachmaninoff, while his older brothers and friends were buying the newest albums of the latest bands. This began his lasting love of classical music.

In 2009, Mr. Sitzler stepped into the professional arena of performing as the Old Gypsy in “Il Trovatore” with Union Avenue Opera. That was followed by premiering the role of Bob in “Family Dynamics” by composer Bill Lenihan with St. Louis City Opera. Among many other programs and performances, Tom participated in the Victoria J. Mastrobuono Emerging Artist Program, in New Jersey, covering Figaro in “Il Barbiere di Siviglia”. In 2012, Mr. Sitzler was heard singing Silvano from “Un ballo in Maschera” with UAO, where Sarah Bryan Miller from the St. Louis Post Dispatch said, “Tom Sitzler … made the most of a small role” and Mark Bretz from Ladue News said, “Tom Sitzler is entertaining as the sailor.” Later that same year, Mr. Sitzler stepped down from a two-year apprenticeship with the Bach Society of St. Louis, where he performed the bass solos in Mozart’s Requiem, and covered the solos in J.S. Bach’s St. Matthew Passion. In 2015, Mr. Sitzler returned to St. Louis to perform the title role in “The Boor” with Gateway Opera, where Mark Bretz from Ladue News said, “As the boor, Tom Sitzler proved his own skills both with his strong singing style and a good way with comedy.”  Most recently, he was engaged as Germont from “la Traviata” and Scarpia from “Tosca” with Painted Sky Opera. www.TomSitzler.com

Artistic Advisor

Roger A. Martinez is a composer who is interested in music that breaks down stylistic and formal barriers, while remaining accessible to a wide audience. He has written for a variety of settings, including opera, art song, electronic works, media music, and online interactive music installations. Roger is a graduate of San Francisco Conservatory of Music’s Technology and Applied Composition program, and has a background in computer science, as well as traditional Western harmony and counterpoint. Roger is second generation Mexican-American, and considers his Mexican heritage to be a point of inspiration for many of his compositions. 

Among Roger’s more recent works are Invocación al Laurel (2021), for string trio and voice, based on the poem by Federico García Lorca, and Climate Works (2020) an interactive web app that translates climate data from around the world into music. In 2019, Roger’s opera Potentialite, written in collaboration with librettist Alize Rozsnyai, premiered as part of the 2019 Philadelphia Fringe fest. Roger's film score credits include A Night Like This (2018), by director Frank Battaglia, and Equity (2015), directed by Andrew Donato. He is currently working on music for an upcoming video game project.

Roger is excited about the musical and narrative possibilities inherent in contemporary opera, and looks forward to writing new works for the opera stage. www.RogerAMartinez.com
