"The Treble Choir of Houston is a first-rate group of young singers...Their sound is a fusion of all that is best in the North American and European traditions. They sing so musically and are mentored beautifully by their Director and Founder, Marianna Parnas-Simpson."

Bob Chilcott



The Treble Choir of Houston at Christ Church Cathedral is an acclaimed ensemble of young women, grades 6-12, that provides outstanding musical training in a nurturing environment. Coming from widely diverse backgrounds, these young women are united in their pursuit of musical excellence.

The Choir's mission is to help each singer realize her full potential as a person and as a musician. Self-esteem, confidence, and leadership skills are cultivated through an environment of love, respect and support.

The Treble Choir was founded in 2006 by Marianna Parnas-Simpson. The Ensemble performs widely in the community and also serves as the resident children's choir at Christ Church Cathedral (Episcopal), Houston. Some of the Choir's performance highlights include Carnegie Hall, the International Choral Festival in Powell River, British Columbia, and the Washington National Cathedral. Treble Choir of Houston was named the finalist of the 2021 National American Prize Competition in Youth Choir Division. The Treble Choir is extremely proud of its association with the Houston Chamber Choir and the opportunities it has had to participate in many of its projects, including the 2020 recording of Bob Chilcott's Circlesong album with Signum Classics.
