Queen might not reign riotously over the whole of Napa Valley, but her benevolence can be felt throughout the region. Queen of the Valley Medical Center has some 190 beds. Part of the St. Joseph Health System, the health care facility provides acute and tertiary care to the residents of California's Napa County. It specializes in family and women's services, work health, and rehabilitation services, as well as trauma, emergency, and urgent care. "The Queen," as it is known colloquially, operates regional cancer and heart centers, the Napa Valley Imaging Center, a breast center, and Nursing Center of Excellence.
