OVERVIEW

Naval Medical Center San Diego (NMCSD), known throughout the fleet as "Balboa," is the U.S. Navy's flagship West Coast tertiary-care medical center. The medical center occupies a 78-acre campus in San Diego's Balboa Park, immediately east of the city's downtown core, and supports more than 270,000 enrolled active-duty, retired, and family-member beneficiaries across the San Diego Navy region — the largest concentration of Pacific Fleet personnel in the country.

NMCSD provides the full range of inpatient and outpatient services found at a major academic medical center, including a verified Level II trauma center, full surgical subspecialties, labor and delivery, a neonatal intensive-care unit, behavioral health, and a comprehensive graduate medical education enterprise. It is the West Coast counterpart to Naval Medical Center Portsmouth and serves as the principal residency-training site for Pacific Fleet Navy Medical Corps (2100), Dental Corps (2200), Medical Service Corps (2300), and Nurse Corps (2900) officers, with residency programs spanning internal medicine, family medicine, surgery, OB-GYN, emergency medicine, pediatrics, psychiatry, and several subspecialties. NMCSD is also the parent command for branch health clinics across the San Diego Navy region under Navy Medicine Readiness and Training Command San Diego.

HISTORY

Naval Medical Center San Diego traces its roots to World War I, when the City of San Diego donated land in Balboa Park to the U.S. Navy to establish a permanent West Coast naval hospital. The original U.S. Naval Hospital San Diego was commissioned in 1922, occupying a Spanish Revival-style hospital complex on the donated Balboa Park site. Through the 1920s and 1930s the hospital became the principal Navy tertiary care center on the U.S. West Coast, treating the rapidly growing Pacific Fleet population.

During World War II the hospital expanded dramatically with temporary wartime structures to become one of the largest naval hospitals in the world, treating tens of thousands of casualties from the Pacific theater. The hospital continued to grow through the Korean War, Vietnam War, and Cold War, and a modern multi-tower replacement medical center campus was opened on the Balboa Park site in 1988, replacing the original 1922 hospital. In the 21st century, the medical center was reorganized under the Defense Health Agency and renamed Navy Medicine Readiness and Training Command San Diego while continuing to operate Naval Medical Center San Diego as its tertiary-care hospital and graduate medical education site. Throughout, the medical center has retained the fleet nickname "Balboa," after the park in which it is located.
