The Family Guide for 2017-2018 is ready
Most of the information in the family guide is now worked into the website pages as a year-round reference. Checkout the Student Portal for most of the information about rehearsals, expectations of musicians, concert etiquette and so on. If you're looking for parent volunteer opportunities, look at the Volunteer page.
But if you prefer to have all the information in one document, you can still download your CYSO Family Guide here.
