You pass them everyday without even knowing it -- hidden by expressway embankments or tucked under an overpass -- homeless people.

Their life is unimaginably difficult but even more so with medical problems. To reach the unreached, volunteer doctors and nurse practitioners visit shelters and search in places one wouldn't expect.

Local 4's Dr. Frank McGeorge went on the street to show us how this caring group gets out of the comfort zone to help people forgotten by most.

Watch his special at 11 p.m. Tuesday and then here on ClickOnDetroit.com when it is posted after the program.
