In the World! Or so some of our “conservative” friends down south tell us.
Free clinics provide care to those who have limited income and no health insurance, including people ineligible for U.S. Medicaid or Medicare programs — a population of at least 8 million. As per Wiki, almost all free clinics provide care for acute, non-emergent conditions. Many also provide a full range of primary care (including preventive care) and care for chronic conditions.
If you have the means and inclination to do so, you can donate to the National Association of Free Clinics here.
