Reunion 2021

We are so excited to celebrate classes ending in “1” and “6” on October 8-9, 2021!

To ensure Reunion 2021 is a safe and special occasion, our schedule will follow a hybrid format. Join us for a virtual morning program and an in-person evening reception on Palm Patio. Castilleja prioritizes the health and safety of our entire community; this change reflects our commitment while aiming to provide a meaningful and memorable reunion celebration. View the updated schedule in the drop-down menu below. 

Please RSVP HERE for both virtual and in-person events.

We hope you will also MAKE A GIFT to help your class compete for the Casti Cup and honor your reunion milestone!


For a discounted rate, please book here by September 6, 2021.
