Mayo Clinic is a not-for-profit organization and a medical practice and medical research group located in 3 metropolitan areas: Rochester, Minnesota, Scottsdale/ Phoenix, Arizona, and Jacksonville, Florida, along with Mayo Clinic Hospitals and some satellite healthcare and research facilities in and near those cities (such as a few nearby satellite primary healthcare facilities and notably the specialty healthcare facility of Franciscan Skemp Medical Center in LaCrosse, Wis.). It is an integral part of the larger Mayo Health System of clinics, hospitals and medical research facilities and schools consisting of Mayo Clinic, Mayo Medical School, the Mayo Graduate School, the Mayo School of Graduate Medical Education, Mayo School of Health Sciences, and several other health science Mayo Clinic partners with a number of smaller clinics and hospitals in Minnesota, Iowa, Arizona, Florida, and Wisconsin. Mayo Clinic specializes in hard-to-treat diseases, and is known for innovative and effective treatments for diseases that had gone undiagnosed or under-treated in the same patients with other doctors. Mayo Clinic is known for being at the top of most accredited quality standard listings. For example, it has been near the top of the US News and World Report of Best Hospitals for 20 years. It accomplishes high medical quality through values such as "The needs of the patient always come first", by coordinating the efforts of its entire group of doctors, and by devoting over 40% of its resources towards research (rather than just medical practice). Mayo Clinic has been on Fortune magazine's “100 Best Companies to Work For” in America list for eight years in a row.
