Welcome! We are the Otter Student Union and we believe that every CSUMB student deserves a place on campus that is welcoming, inclusive, and provides opportunities to enhance their college experience. We inspire connection, foster growth, and cultivate memorable moments for every individual in our vibrant community. Our building is designed with dynamic areas to cater to a broad range of student interests and needs, making us a hub for social activities, quiet reflection, dining options, and more. We are the heartbeat of campus, the home away from home, and you belong here at the OSU.
