Eastern Bank, a Boston-based bank with $8 billion in assets and roughly 90 branch offices, said it has provided $15 million of New Markets Tax Credit financing to facilitate Caring Health Center’s acquisition of a new building that will double the existing space of the Springfield health center.

Caring Health Center seeks to provide health care to those who are challenged by social-economic, linguistic, and cultural barriers. Since opening in 1995, it has grown from a staff of four to 150 employees.

Also participating in the deal were Massachusetts Housing Investment Corp., Building America, the Life Initiative, and the Health Resources and Services Administration.
