Cantor Jaime Murley joined the Beth Or clergy team in 2012. She started her career at Beth Or working alongside Cantor David Green as adjunct cantor, and is honored to follow in his footsteps as the congregation’s cantor, supporting the congregation’s musical and spiritual needs. Developing an early love for music of all kinds, Cantor Murley received a Masters in Percussion Performance in 2000, and pursued a career as a classical percussionist, where she played in symphony orchestras both locally and internationally. In 2002, she discovered the beauties of Jewish music and decided to switch gears. In May of 2009, she 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, whereupon she came to Beth Or and the rest is history! Cantor Murley loves helping people connect to Judaism through song and prayer, whether be in one of the Congregation’s choirs, musical groups, or through worship.  She is thrilled to work alongside the amazing staff and talented clergy team at Congregation Beth Or. 

Cantor Murley is married to Luke Murley and they reside in Wallingford, Pa with their three children, Cooper, Noa and Darwin.


Cantor David Green, Cantor Emeritus 

Cantor David Green served as Beth Or's Cantor from July 1995 until his retirement in June 2022. His magnificent, bellowing baritone voice was equaled by his kind, compassionate personality, which made him beloved by congregants across the generations, including the thousands of B'nai Mitzvah children and adults he tutored throughout his tenure. His experience spanned worship, life cycle events, pastoral care, support groups, music and education.
