Truong Van Dinh is a boy who won the Reading Digest's essay competition that Lisa competed in. His essay's name is USA A-OK, in which he thanks the freedom of economic opportunity that was unlike his heavily-regulated native country, which allowed his family to rise from penniless immigrants to successful business owners.


Lisa was introduced to him by Faith Crowley. He has won both the Westing House talent search and the NFL punt, pass and kick competition. He later went on to win the essay competition, then he congratulated the losing competitors for trying, and said Lisa's essay exposing Bob Arnold's corruption was deserving of special praise.
