The Heartbeat of Campus


The University Student Union (USU) at Cal State San Marcos welcomes all students and the campus community to the Spring 2021 semester. Everything the USU provides for you is intended to optimize your sense of belonging at CSUSM through student engagement, connection and community building. 

Due to the COVID-19 pandemic, full access to the USU is currently suspended, however we are committed to providing exciting virtual events, programs and services for students.

In order to provide critical access to computers, printing service, power and Wi-Fi, the USU is excited to partner with IITS to provide a Computer Lab in the ballroom and meeting spaces. For more information please visit the USU Computer Lab page.
