Annual Orchestra Dinner & Concert Event!

Each Fall, all of the Orchestra classes together select a Theme and then perform music based on that theme in an extravagant Orchestra Dinner & Concert event. It is a special night where each of the strings classes demonstrate their talents for their families and friends! 

In addition to a catered dinner, there is also a large Silent Auction for attendees to bid on throughout the evening with winners announced at the conclusion of the concert. 

100% of proceeds collected at this event go to the Tesoro Music Department!
