Kaleida Health Headquarters & Corporate Office

About Kaleida Health

Kaleida Health was formed in 1998 through the consolidation of major Western New York hospitals and healthcare organizations, although the individual institutions that make up the system have histories extending back more than 170 years. The consolidation created a large nonprofit healthcare system designed to coordinate hospital operations, specialty services, community care, and regional medical resources across Buffalo and the surrounding area. Over time, Kaleida expanded through affiliations, hospital combinations, physician partnerships, home-care operations, and broader regional integration.

Today, Kaleida Health is one of the largest healthcare systems in Western New York and a major teaching affiliate of the University at Buffalo. Its network includes Buffalo General Medical Center and Gates Vascular Institute, Golisano Children’s Hospital of Buffalo, Millard Fillmore Suburban Hospital, DeGraff Medical Park, Bradford Regional Medical Center, Olean General Hospital, long-term and rehabilitation facilities, home-care organizations, and numerous outpatient services. Current 2026 system information reports 11,863 employees including Twin Tier operations, 1,579 affiliated physicians, approximately 80 outpatient clinical locations or departments, and $2.53 billion in 2025 operating revenue.

Kaleida Health remains a nonprofit healthcare organization rather than a publicly traded hospital company. It is affiliated with Great Lakes Health System of Western New York, which helps integrate Kaleida Health, Erie County Medical Center, and the University at Buffalo. The organization continues expanding coordinated care across Western New York and northwestern Pennsylvania while maintaining its principal corporate presence at 100 High Street, Buffalo, New York 14203. There has been no recent acquisition converting Kaleida into a private or investor-owned hospital company.
