"At Justin-Siena, 60 years of community comes down to five principles”

We are proud to call the greater Napa Valley our home since opening the doors in 1966!

As excerpted from today’s Napa Register:

“But the milestone isn’t really the story.
It’s five principles painted on classroom walls and on posters throughout campus — respect for all persons, inclusive community, holy presence of God, quality education, concern for the poor and social justice.”
