Amy has been associated with the Music Together brand for over 14 years as a Music Together instructor. She has been awarded Music Together Certification Level I status, having demonstrated outstanding achievement in teaching, musicianship, program philosophy, and parent education by the Center for Music and Young Children in Princeton, NJ. Now, as a Licensed Center Director, Amy continues to bring her love of singing, silliness, and family music making to every class. Amy received the Doctor of Musical Arts degree with an emphasis in Opera Performance from the University of Texas at Austin in 2005, and continues to perform opera as a member of the Chorus of Opera Company of Philadelphia. In her free time, she enjoys performing Broadway and cabaret music with her husband, and singing silly songs and lullabies with her three children. Her favorite way to sing any song - no matter the style - is on chicken noises. Try it! You're guaranteed to laugh!
