2023–2025 Campus Plans

Castilleja's Home Away from Home

After much consideration and careful planning, we have found an amazing new home-away-from home at 3055 Clearview Way in San Mateo, and we will be using space at neighboring College of San Mateo to support co-curricular programs. 3055 Clearview is a warm and inviting building with gorgeous views and a variety of different spaces that we will use for classrooms, offices, learning hubs, gathering spaces, and patios. It is also very convenient to get to, close to both 101 and 280, and opens up new learning opportunities and partnerships in San Francisco, Half Moon Bay, and the East Bay.  To learn about our robust transportation options, including our bus and shuttle offerings, click here.

We will return to our modernized campus in August 2025; learn more here!
