GILROY—Dozens of workers at Saint Louise Regional Hospital, from its chief of staff to its nurses, along with citizens and elected officials spoke of the need to keep the Gilroy hospital open at a hearing hosted by the California Attorney General’s Office. The Oct. 16 session at Gilroy City Hall was one of a handful held in California as Attorney General Kamala Harris reviews the proposed sale of Saint Louise and five other hospitals to New York-based private equity firm BlueMountain.
