Since Mayo's establishment in 1863, Mayo's renowned reputation began with their exceptional team approach practice to patient care.

In a recent study, 88 percent of patients who came to Mayo Clinic for a second opinion received a new or refined diagnosis.

In addition, Mayo is also equipped the latest in diagnostic and treatment technology ― from the highest resolution imaging devices to robotic surgery.

Patients traveling internationally are provided timely diagnostic and specialty care in a place designed to feel a little more like home. At Mayo, patients have access to all medical and surgical sub-specialties within a single institution, empowering the medical team to address all the patient's health needs and treat the whole person.
