As a graduate of Houston’s High School of Performing and Visual Arts (HSPVA), Stephen began exploring his passion for music very early. Singing in numerous choirs across the city and his church since he was a child, his voice has had both gospel and classical training. He used his training to pursue and receive a Bachelors of Arts in Music Education from Loyola University in Louisiana. Once he obtained his degree, Stephen made a decision to use his knowledge to teach in the public school system. Stephen was offered a position in Houston with the Sheldon Independent School District, where he served as overseer of secondary choral music. He was directly responsible for teaching music theory and appreciation to grades 9-12, and promoting and recruiting for the music program of the high school. He also wrote and directed seven outstanding musicals with the students of C.E. King High School. During his fourth year with Sheldon ISD, Stephen decided to take his educational career to another level by starting and finishing the graduate program with the University of St. Thomas. During his time in New York City, he was an active singer, director, teaching artist and producer. He worked as a teaching artist with the Dreamyard Project of New York, focusing on music directing and voice teaching for Bronx youth. Simultaneously, he worked with Broadway's Babies, a not for profit organization that collaborates with the Broadway community to provide performance and music education to underserved communities both nationally and internationally. Through that relationship, he became Co-director of the New York City Youth Pride Chorus for two years. The director, voice teacher, producer has returned to Houston and is very excited to be working with I Colori Dell'opera. |
