Undercover doctor for the homeless

For more than 20 years, Dr. Jim Withers has taken his medical practice to the streets of Pittsburgh, Pennsylvania, offering free, quality health care to the homeless.

Photos: Bringing 'street medicine' to the homeless For 23 years, Dr. Jim Withers has been doing street rounds in Pittsburgh, Pennsylvania, bringing medical care to the homeless. Hide Caption 1 of 7 Photos: Bringing 'street medicine' to the homeless When he started in 1992, he dressed like a homeless person in order to connect with the men and women who had been excluded from his care. "I was actually really shocked how ill people were on the street. It was like going to a third-world country," Withers said. Hide Caption 2 of 7 Photos: Bringing 'street medicine' to the homeless Withers' one-man mission has since expanded to a citywide program called Operation Safety Net that includes a mobile van, drop-in centers and a primary health clinic, all where the homeless can access medical care. The group also does home visits to people who have transitioned off the streets. Hide Caption 3 of 7 Photos: Bringing 'street medicine' to the homeless Withers and his group have reached more than 10,000 individuals and helped more than 1,200 of them transition into housing. Withers met Lois -- pictured here, receiving a home visit -- when she was living on the streets. Hide Caption 4 of 7 Photos: Bringing 'street medicine' to the homeless Medical students come from all over the country to work with Withers and Operation Safety Net. "When (students) can see a street person succeed and not just get locked in that hopeless category, their vision changes. The street classroom really ignites, or reignites, what their passion is. ... And they carry that forward." Hide Caption 5 of 7 Photos: Bringing 'street medicine' to the homeless Withers is also fostering a global "street medicine" movement through his nonprofit, the Street Medicine Institute, which supports communities in starting programs of their own. "In the way I'd like to see things, every person who is still on the streets will have medical care that comes directly to them and says, 'You matter.' " Hide Caption 6 of 7 Photos: Bringing 'street medicine' to the homeless Withers: "It's something that we should take pride in when we can actually treat people the way we would want to be treated." Hide Caption 7 of 7

To win their trust, Withers used to walk the streets dressed like a homeless person — rubbing dirt in his hair and muddying up his clothes. He would search for those who needed medical attention who might be too suspicious of him otherwise. It was important for Withers to connect with people who wouldn't seek him out. Instead, he reached out to them.

"I was actually really shocked how ill people were on the street," Withers said. "Young, old, people with mental illness, runaway kids, women (who) fled domestic violence, veterans. And they all have their own story."

Withers' one-man mission became a citywide program called Operation Safety Net . Since 1992, the group has reached more than 10,000 individuals and helped more than 1,200 of them transition into housing.

He also started Street Medicine Institute , a nonprofit that helps communities worldwide establish programs of their own.

The group rescued 200 animals, including around 160 sloths. They jokingly called it "Slothageddon -- sloth armageddon." "During that time, it was really a bit weird to live here because there were sloths everywhere: in my living room, in cages, in my garage. Dozens of volunteers were helping."

Babysitting money transforms entire community

A New Jersey woman who saved her babysitting money has made a difference half a world away in Surkhet, Nepal. Ten years ago Maggie Doyne decided to backpack around the world before college. But during a stop in Nepal, her life took an unexpected turn. She met women and children who were struggling to survive the aftermath of a decade-long civil war.

'Walking off the war'

Iraq and Afghanistan combat veteran Sean Gobin's nonprofit, Warrior Hike , has a unique way to help combat vets process their troubling war experiences. Gobin calls it, "walking off the war." The idea came during a 2012 hike along the 2,168-mile Appalachian Trail.

"Hiking eight hours a day, I was processing all of these experiences that I had put away," said the Charlottesville, Virginia, native. "And I knew that there were other combat veterans that needed to do that."

Bringing water to drought-stricken people

For CNN Hero Bhagwati Agrawal, it was a water crisis in his homeland that spurred him to act. His nonprofit, Sustainable Innovations, created a rainwater harvesting system that now provides life-changing, safe drinking water to more than 10,000 people across six villages in the driest region of India.

Hide Caption 1 of 7 Photos: Harvesting rainwater for India's driest region Aakash Ganga is a network of rooftops, gutters, pipes and underground reservoirs that collect and store the monsoon rains.

Hide Caption 2 of 7 Photos: Harvesting rainwater for India's driest region "Growing up, every morning I accompanied my mother to fetch water—a daily ritual," Agrawal said.

California's record-breaking drought has made news, but in Rajasthan, water scarcity is a way of life. Women and children walk miles to get water and clean dishes with sand to conserve it. His system, called Aakash Ganga -- Hindi for "River from the Sky" -- is a network of rooftops, gutters, pipes and underground reservoirs that collect and store the monsoon rains, which fall from July to September.

The system frees adults to spend time doing more valuable activities. Not having to fetch water allows children, especially girls, to spend more time in school. People report fewer health problems. Dairy cows have become twice as productive.

"The way I look at it, I'm 70 years old" Agrawal told CNN. "I only have maybe 10 years left of active life. Right now I'm like Usain Bolt, the sprinter. ... And I will run very fast to accomplish this mission."

Fulfilling a promise to her Native American grandmother

Growing up, Rochelle Ripley spent her summers listening to her grandmother's stories. Her grandmother, a full-blooded Lakota, taught her about their culture and the struggles faced by the people. Before her grandmother died, she asked Ripley to do one thing: Go home and help their people.

Today, Ripley is fulfilling that promise. Through her nonprofit, hawkwing , she has delivered an estimated $9 million in services and goods to the Lakota people.

Being there for single parents with cancer

For single parents, dealing with cancer offers its own set of challenges. Jody Farley-Berens saw the need firsthand, when her childhood friend faced that situation.

"Making ends meet is insurmountable," said Farley-Berens. "There are so many doctors' appointments, copays, surgeries, prescriptions. And then the inability to work -- any savings that there may have been is gone very quickly."

She did all she could to help. After her friend passed away, Farley-Berens helped start a nonprofit dedicated to assisting others in similar circumstances.

A 'battering ram' for patients

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

Today, Ivankovich runs three clinics in Chicago and performs more than 600 surgeries a year. He says more than 100,000 people have benefited from the program.
