St. Joseph Mercy Hospital

Our MercyOne North Iowa Story

  • The Sisters of Mercy opened St. Joseph Mercy Hospital in Mason City in 1916. Their efforts to care for the growing community augmented those of a group of local doctors, who had established Park Hospital seven years earlier.
  • Park later was renamed North Iowa Medical Center and was moved from its downtown location to the west side.
  • The hospitals consolidated in 1993 to become Mercy Medical Center North Iowa, known today as MercyOne North Iowa Medical Center.
