Multidisciplinary teamwork with coordinated care is Mayo Clinic's secret sauce. The not-for-profit Mayo Clinic provides health care, most notably for complex medical conditions, through its clinics in Rochester, Minnesota, Arizona, and Florida. The clinics' multidisciplinary approach to care attracts more than a million patients a year from around the globe. For less specialized care, the Mayo Clinic Health System operates a regional network of affiliated community hospitals and clinics in Minnesota, Iowa, and Wisconsin. Mayo Clinic also conducts research and trains physicians, nurses, and other health professionals. The Mayo Clinic is named for Dr. William Worrall Mayo, who settled in Rochester in 1863.
