United Sound is an organization whose mission is to provide musical performance experiences for students with special needs.

Who We Are

Julie Duty, Founder and Executive director

The most common question Julie is asked about United sound is, "WHY?" This is her answer.

Julie completed her undergraduate degree at Arizona State University in 1998, earning a Bachelor of Music in Music Education. She taught middle school band and served as a mentor teacher for nine years in Arizona. During that time her groups were recognized for musical excellence and had active involvement with Special Olympics Arizona, performing for their annual opening ceremony event.

Since leaving the classroom, Julie has remained dedicated to music education and community service. She is an active volunteer with Sunshine Acres Children’s Home in Mesa, Arizona, working as a grant writer and executive assistant. She volunteers within her church community as the leader of a regional orchestra and leads a 150 member children’s chorus. Julie also spends many hours each week volunteering in her local school district. She co-founded a parent advocacy group, Gilbert Music Matters, which works to bring parents and school district leaders together to improve music education.

Julie currently serves as the founder and executive director of United Sound, Inc. working with teachers, parents, and school administrators to bring meaningful participation and inclusivity to the instrumental music classroom. Julie is still an active musician, performing in the Tempe Symphonic Wind Ensemble for the past eighteen consecutive years. She works regularly for the Arizona Band and Orchestra Director’s Association as a judge and adjudicator for state-wide events. And is a mother to three adorable musicians of her own.
