Health Alliance History

For over 35 years, Health Alliance has been working to help members be their best.

Health Alliance began serving members in East Central Illinois in 1980, under the name CarleCare HMO. In 1989, the name was changed to Health Alliance Medical Plans, and it was reorganized as a for-profit insurance company owned by Carle Clinic.

In 1995, Health Alliance Midwest was formed to offer our quality insurance and customer service in Iowa. In 2013, Health Alliance Northwest brought our Medicare plans to Washington. Health Alliance is now the largest health plan in downstate Illinois. Under The Carle Foundation, Health Alliance is proud of its long history of bringing outstanding coverage and customer service to the area and is excited to continue helping more people get quality insurance.
