LivDelicious Helena Medena interviews Darryl Vincent.

Darryl Vincent lives by the motto that the "best way to take away someone's dignity is to do something for them that they can do themselves." Vincent, recently promoted to division director for the United States Veterans Initiative in Hawaii and California after running the Hawaii sites since 2003, has a phone that rings "24-seven," by his own estimation. But it's for a good cause.

U.S. Vets is the largest nonprofit provider in the country for homeless veterans. It offers a variety of benefits and services, including temporary and low-income housing, food, clothing, job training, substance-abuse treatment and counseling. The success rate is impressive: 80 percent will have full-time employment when they finish the program.
