Maryland Teen Among America's 2019 Top 10 Volunteers Faiza Elmasry CROFTON, MARYLAND --Reading the biography of a philanthropist was a life-changing experience for Caleb Oh. The book was so inspiring that he wanted to volunteer with a local charity, but there was a problem. Caleb was only 6 years old. "What I found out was almost all organizations had age restrictions," recalls Caleb, who is now 14. "You have to be at least 8 years old to volunteer. This frustrated me." Caleb's parents were saddened to see their young child frustrated. "For me and my husband, it was a time to kind of think and brainstorm with him on how he might be able to help," his mother, Margaret Oh, said. The parents told the 6-year-old he could start a nonprofit organization and that's what Caleb decided to do. .
