Third-year medical students train within a broad network of community hospitals and regional medical centers. These include the public safety net hospitals in Riverside County and San Bernardino County, private general acute care medical centers, community hospitals, a non-profit integrated health plan, two behavioral health centers, a Veterans Administration facility, and a state-operated forensic psychiatric hospital. This ensures that students will have educational experiences with the diverse patient populations of the Inland Southern California region.
