It’s a daunting figure, but Littleton-based nonprofit Doctors Care is trying to address the problem. Nine hundred physicians donate their time to the organization to treat more than 5,500 patients in Douglas, Arapahoe, and Elbert counties who lack private insurance. Lend a hand by contributing financially, committing some office hours, or, for those trained in medicine, volunteering at the Doctors Care clinic. doctorscare.org
