A group of Long Island residents recently returned from a trip to Greece, where they spent their time helping tens of thousands of Syrian refugees.

Bob Miller, a lifeguard from Montauk, spent much of his time helping people in rickety, overcrowded boats.

"It was 50 people in a boat sinking. I knew I couldn't save all of them," says Miller.

Denise Schoen, an EMT from Sag Harbor, spent a lot of time with children. She says her most memorable moment was detecting a heart condition in a young girl and being able to get her medical attention.

Others say the experience was life-changing, describing the refugees as thankful for their help.

Many of the volunteers say they will be heading back to the region in an effort to aid the refugees. Several organizations are raising money to send supplies to sponsor volunteers.
