“Uncovered California” is a three-part series of stories and videos examining how the Golden State is trying to fill holes in its health care coverage. Sasha Abramsky’s two stories focus on Californians who are falling through coverage cracks, and on what’s being done to help community college students gain access to mental health services. Debra Varnado reports on efforts to expand the role of nurse practitioners to increase medical services for low-income Californians.
