Jordanian-born Shireen Abu Khader is currently residing in Toronto and working on obtaining her PhD in Music Education. After obtaining a Bachelor of Arts in Music Education from Oberlin College Conservatory in 1994 and a Master's degree in Choral Music from the University of Southern California in 1998, she moved to Palestine where she taught music for several years. In 2002, she founded Dozan wa Awtar Music Establishment.

Shireen's inspiration for this establishment stemmed from her work with The Edward Said Conservatory in Ramallah, Jerusalem, and Bethlehem from 1998 to 2000. During this time she worked with local children choirs and youth orchestras on several projects. In Palestine, she worked with a group of men who called themselves "Dozan", and a group of women under the name of "Awtar" and Shireen decided not to limit the choral experience to Western music. After founding DwA Music Establishment, Shireen reshaped the choir’s mission, and with that in mind, every show seeks to inspire, create, unite, and respond to the changing socio-political context. Besides her choral work, Shireen has been involved in orchestral conducting and holding workshops for teachers at schools, colleges, and refugee camps in Jordan and the West Bank.
