From musical theatre greats, Stephen Schwartz (Wicked, Godspell) and John Caird, comes a joyous and inspirational musical about parents, children, and faith... not to mention centuries of unresolved family business! Adam, Eve, Noah, and the "Father" who created them deal with the headstrong, cataclysmic actions of their respective children. The show ultimately delivers a bittersweet but inspiring message: that "the hardest part of love... is letting go."

Please join the Justin-Siena Choral Department for a musical celebration at our annual winter concert, “Thankful.” Located at the beautiful Mont La Salle Chapel on Saturday, December 9, there are two shows, at 3pm and 7:30pm. Enjoy a wonderful selection of holiday and sacred music as well as the spirit of giving as we gather food items for the Napa Food Bank.

Robert Louis Stevenson’s classic tale of murder, money, and mutiny is brought to life in this imaginative adaptation, which keeps alive the wit and excitement of the book. Treasure Island is a breathtaking yarn of piracy on the high seas.

It begins at an inn on the Devon coast of England in 1775 where young Jim Hawkins longs for adventure. Soon Jim’s searching for a chest full of gold and off the most infamous pirates of all .me, including Black Dog, Anne Bonney, and the foulest of them all, Blind Pew. At the center of it all is Long John Silver, perhaps the most famous hero- villain of all time.
