Providing health care to uninsured

I am a certified substitute teacher in Illinois who does not receive health benefits through my employer(s). I've done much exploration of subsidized health care services in the Chicago area; the wait can be months or even years. I've developed an interest in coordinating services, such as itinerant dental services, to uninsured residents in high-need areas, not necessarily in Chicago. This could be a traveling clinic staffed by volunteers. Has anyone else thought of doing something like this? I'd be interested in connecting with anyone else who was interested. Michelle
