The Mayo Clinic: Faith - Hope - Science tells the story of a unique medical institution that has been called a "Medical Mecca," the "Supreme Court of Medicine," and the "place for hope where there is no hope." The Mayo Clinic began in 1883 as an unlikely partnership between the Sisters of Saint Francis and a country doctor named William Worrall Mayo after a devastating tornado in rural Minnesota. Since then, it has grown into an organization that treats more than a million patients a year from all 50 states and 150 countries. Dr. Mayo had a simple philosophy he imparted to his sons Will and Charlie: "the needs of the patient come first." They wouldn't treat diseases...they would treat people. In a world where healthcare delivery is typically fragmented among individual specialties, the Mayo Clinic practices a multi-specialty, team-based approach that has, from its beginnings, created a culture that thrives on collaboration.
