About the Department

The Department of Clinical Education at California Northstate University, College of Medicine is dedicated to preparing students for the transition from classroom learning to patient-centered clinical practice. Through our comprehensive clerkship program, students gain hands-on experience across core medical disciplines under the mentorship of skilled clinical professors and community preceptors. We emphasize strong partnerships with regional hospitals, clinics, and healthcare systems, ensuring our students are guided by expert physicians and exposed to a diverse range of patient care experiences. Our commitment is to foster clinical excellence, professional growth, and compassionate care as students progress through their medical journey.
