NILES — Cassopolis Family Clinic Network has received a $300,000 donation from Spectrum Health Lakeland for the new Niles Community Health Center facility that opened in November.

The facility at 1951 Oak St., opened its doors in 2014, just as Michigan expanded Medicaid to nearly 670,000 low-income state residents. Most were people who had no regular source of health care, and used the emergency room when they were sick, according to a news release.
