GHI (Group Health Incorporated) was established in 1937 as Group Health Association of New York, a small health cooperative with a handful of subscribers and premiums of less than $2,000. Over the years, Group Health Association of New York was successively called Cooperative Health Association of New York, Group Health Cooperative, Group Health Insurance and, since 1971, Group Health Incorporated.

GHI has pioneered some of the most popular and affordable health insurance models in use today, and continually works to raise public awareness of important health issues.

After 66 years, GHI has grown into the largest statewide not-for-profit health insurance corporation, offering a full range of medical, hospital, dental, mental health, vision, and prescription drug coverages. GHI currently provides services for more than 2.5 million individuals.
