Cantor Jamie Murley

Adjunct Cantor and Junior Choir Director



Cantor Jaime Murley was born and raised in Philadelphia, PA. Developing an early love for music of all kinds, she pursued a career as a classical percussionist in symphony orchestras. In 2002, she discovered the beauties of Jewish music while teaching religious school. After teaching for just one year, she decided that she needed to know more about it, and she enrolled at Gratz College to pursue another Masters – this time in Jewish music. In May of 2009, Jaime graduated Gratz College with a Masters of Arts in Cantorial Studies and Jewish Music while serving as cantorial intern at Congregation Rodeph Shalom in Philadelphia throughout her schooling. Upon her graduation, Jaime served as cantor of the synagogue through the spring of 2012.

Jaime's specialty lies in accompanying herself on guitar while bringing participatory music to services, and working with children of all ages in the hopes of connecting them to their Jewish heritage through song.
