Recognizing their good deeds, President Barack Obama yesterday awarded the nation's second-highest civilian honor to 13 compassionate Americans for their decades of service helping the poor, illiterate, disabled, and war-weary.

"They all faced that moment when you see a neighbor in need and you have to ask yourself a question," said the President in a White House ceremony. "They are united by the choices they've made. They could have made excuses for doing nothing. Instead, they chose to help."

This year's winners of the Presidential Citizens Medal included Americans from all walks of life.

John Keaveney, a Scottish immigrant, served two tours in Vietnam before coming back to establish a home for homeless and disabled veterans with addiction and mental health problems. Roberto Perez is an ordained Methodist pastor who counsels inmates and is president of a nonprofit organization that has taught more than 7 million people to read worldwide. After watching gang members stop to watch a young boy play his violin at the farmer's market, an L.A. resident, Dr. Michelle Martin, founded an organization that connects kids in underserved communities with instruments and music lessons.

The 13 medal-winners were selected from 6,000 citizens nominated by the public:
