It was acquired by Columbia/HCA in 1996; Tenet Health Systems in 1999; Vanguard Health Systems in 2009; and once again Tenet Healthcare Corp. in 2013 when Tenet acquired Vanguard. MWMC also operates an outpatient diagnostic and rehabilitation facility, MetroWest Wellness Center, in Framingham. MetroWest is affiliated with the Tufts Children's Hospital.
