On July 1, Group Health will open Bellevue (WA) Medical Center, a four-floor, 190,000-square-foot building. The medical center is intended to provide care for more than 1,000 people a day who will come for outpatient treatment. Some will have surgery there, but if Group Health patients need to spend the night, they'll do so at Overlake Hospital Medical Center. The two facilities will be connected by a tunnel.
