In Chicago's troubled neighborhoods, Dr. Daniel Ivankovich witnessed countless people struggling to get medical treatment because they were under-insured or they didn't have any insurance at all. They were put on wait lists for months, even years, just to receive basic procedures, and their injuries got worse.
"I thought to myself, this is happening in America?" he said.
So Ivankovich vowed to treat patients regardless of their ability to pay. In 2010, he co-founded the nonprofit OnePatient Global Health Initiative.
