The Northwest Iowa Symphony Orchestra is comprised of the finest musicians in the tri-state area. The orchestra membership includes adults of all ages as well as gifted music students from area high schools and colleges. Several of the high school students in NISO receive scholarships to continue their private music lessons.

Over 25 students from Dordt University Music Department are members of the orchestra and several members of the Dordt University music faculty perform as teaching principals in the orchestra. NISO presents three concerts per season in addition to the annual Concert for Children which is given each November for over 1000 area 4th/5th/6th grade students.

All concerts are performed at 7:30 PM in the beautiful B.J. Haan Auditorium on the campus of Dordt University in Sioux Center, Iowa. NISO/NISYO is made possible by the generous support of Dordt University, Sioux Center Recreation and Arts Council, Friends of the Symphony, and individual patrons, organizations and business establishments.
