The Service League of Northwest Indiana Fund supports nonprofit organizations providing services to Lake County, Indiana families, individuals, and communities.

On July 2, 1935, Mrs. Frederick Crumpacker invited a group of Hammond women to a tea for the purpose of forming a support group for the Bethany Home for Children.

The Bethany League changed its name and incorporated as The Service League of Hammond on May 2, 1938. This organization has now become known as Service League of Northwest Indiana because its interests and services were expanded to include other charitable organizations in the Northwest Indiana region.
