The Kalamazoo Junior Symphony Orchestra (KJSO), the flagship ensemble and namesake of the organization, is led by Andrew Koehler, who also serves as a professor of music at Kalamazoo College and is the music director of the acclaimed Kalamazoo Philharmonia. In addition to the KJSO’s three annual performances of professional-level repertoire in historic Chenery Auditorium, the KJSO also tours internationally, and offers a dynamic chamber music training program for select KJSO members who are coached by area professional musicians.
