Meet Our Community

At Justin-Siena we pride ourselves on the Lasallian Catholic heritage that guides our mission.  As an inclusive community we celebrate the wide range of diversity we enjoy here.  We have 650+ students who are diverse in their heritage, backgrounds, and passions. They come from nearly 40 different previous schools, 20 countries, and 3 counties joining together to be one ALLHEART community. 

Justin-Siena's diversity is what makes it a richly vibrant and special school.  In the traditional sense, 55% of our students report being from a diverse background. We know and see diversity in a much broader context: geographics, experiences, perspectives, backgrounds, passions, and talents.
