Iris Munoz and Isabella Izidoro greeted guests as they entered the newly named CHA Everett Hospital, which has changed its name from the Whidden Hospital. The Whidden was donated to the City of Everett many years ago to be set aside for a hospital. Now, as part of the Cambridge Health Alliance (CHA), the hospital sought to be consistent in its branding. The name officially changed on Nov. 1 and a ceremony to celebrate the change took place on Tuesday, Nov. 15.
