    Athletic stadium and newly renovated gymnasium

Located on a safe, residential, 40-acre campus in Napa Valley, the Justin-Siena campus offers students everything they need to grow as students and become successful. The Justin-Siena facilities include scientific and academic classrooms, an athletic stadium and a performing arts center. Students live in an on-campus dormitory with a swimming pool and have full access to the school grounds and facilities. Justin-Siena’s academic facilities include advanced classrooms equipped with SMART technology, Apple TV's, 3D printers, and wireless internet. New renovations to academic wings give students the flexibility to work in classrooms, small group meeting spaces, or seminar rooms when necessary. If students choose to work in a more social environment, the student center is a large, comfortable space with computers, printers, multimedia access, and study rooms. All athletic teams have dedicated spaces for practices and competition. Students can train in the newly renovated gymnasium, weight room, and are able to utilize locker rooms to store equipment. In addition, the school provides an athletic trainer on campus for athletic support.
