Blue Cross and Blue Shield of Ohio

Medical Mutual of Ohio is a prominent health insurance provider and the oldest insurer headquartered in the state of Ohio. Founded in 1934, the company offers a diverse range of products including health, dental, vision, life, and disability insurance to individuals and employer groups. For much of its history, it operated as Blue Cross and Blue Shield of Ohio (BCBSO) before a high-profile legal dispute with the Blue Cross Blue Shield Association led to a rebranding in 1997. As a mutual company, it is owned by its policyholders, which allows it to prioritize member services and long-term financial stability over shareholder profits. Today, it serves approximately 1.6 million members and maintains a robust network of healthcare providers throughout the region.
