Mayo Clinic

Mayo Clinic in Rochester, Minnesota was founded in 1889 and has grown into one of the largest and most cited academic medical centres in the world, consistently ranked first or second in U.S. News & World Report's annual Best Hospitals survey. The campus spans approximately 14 million square feet and houses more than 60 specialty departments, making it a destination for patients with complex or rare conditions that have not been resolved elsewhere. Mayo receives patients from all 50 states and over 140 countries, and operates a dedicated International Services department to coordinate care pathways, visa documentation, translation services, and financial estimates for international visitors. The institution is particularly recognised for its integrated multi-specialist consultation model, in which teams of physicians from different disciplines evaluate a patient concurrently rather than sequentially, reducing total diagnostic time. Flagship clinical areas include oncology, transplantation, cardiac surgery, neurology, and rare endocrine disorders. Mayo also operates one of the most established Proton Beam Therapy programmes in North America. Patients seeking second opinions on major diagnoses represent a significant share of international referrals. The facility is accredited by both the Joint Commission and JCI.
