Orchestra

Welcome, Interlake Orchestra Students and Families!

We are excited about this year and all of the fun things that are going to happen! Interlake Orchestra consists of three ensembles: Concert Orchestra (freshmen and first-year orchestra students), Sinfonia Orchestra (non-audition 10th-12th graders), and Chamber Orchestra (audition 10th-12th graders).

We will be updating this page all year long with news, information, photos, and videos from this year’s events and performances.

The 2025-26 IMPA contacts for Orchestra are:
Co-VPs: Makiko Hirai, Lisa Okahata, and Qi Zhang
Orchestra Music Director: Dr. Shira Katsman (katsmans@bsd405.org)
