First Friday Lunches

The Alumni Association hosts quarterly First Friday Lunches for alumni to network with one another and reconnect with Castilleja teachers.

Meet in the Gunn Administration Lobby to check in for lunch, and we will walk over to lunch together. We offer informal campus tours following lunch for anyone who is interested.


Special Events

We have many annual special events for the whole alumni community to enjoy, including our Volunteer Day, Family Valentine's Day Party, and Founder's Day!
