Mayo Clinic is a non-profit medical practice. Its headquarters, the Mayo Medical School and its research facilities are in Rochester, Minnesota in addition to hospitals and clinics in Jacksonville, Florida and Scottsdale, Arizona. Mayo Clinic partners with a number of smaller clinics and hospitals in Minnesota, Iowa, and Wisconsin, an organization known as the "Mayo Health System".

For historical reasons, the institution is referred to as "Mayo Clinic", rather than "The Mayo Clinic" or "Mayo's Clinic." The clinic started as a single small outpatient facility.

Mayo Clinic pays medical doctors a fixed salary that is unaffected by patient volume. Salaries are determined instead by the marketplace salaries for physicians in comparable large group practices.

History

Mayo Clinic evolved from the frontier practice of Dr. William Worrall Mayo (1819–1911) and his two sons, William James Mayo (1861–1939) & Charles Horace Mayo (1865–1939). Dr. William Worrall Mayo emigrated from Salford, United Kingdom, to the United States in 1846 and became a doctor.

The Mayo Clinic founders are Drs. Mayo, Dr. Stinchfield, Dr. Graham, Dr. Henry Plummer, Dr. Millet, Dr. Judd, and Dr. Balfour. These early partners shared in the profits of the private group practice, while other staff hired by the partners were salaried. In 1919, this group created the Mayo Properties Association, and their private practice become a not-for-profit entity. The Mayo brothers, who had retained ownership of all the Clinic properties and furnishings, gave everything to this newly formed association. The integrated group practice has it roots firmly planted in this early private practice and partnership.

In 1892, Dr. Augustus Stinchfield was asked to join the practice by Dr. Mayo, who considered him to be the best doctor in the small towns near Rochester. Once Dr. Stinchfield joined the practice, Mayo retired at the age of 73.
