Established in 1986, Dignity Health (formerly Catholic Healthcare West) is one of the largest healthcare networks in the U.S., with 10,000 physicians and 55,000 employees across Arizona, California, and Nevada. They changed their name and logo in January. Press release here [PDF]. Logo explanation: “The logo represents the coming together of caregivers, services, care centers, etc., to create a continuum of care. The three sections remind us of the three dimensions of our mission — healing, advocacy, and partnering. The icon surrounds a central space, symbolizing how an integrated health system honors the inherent dignity of each individual.”
