Maroun works for Roche Bros. in Downtown Crossing. She practices for about an hour a day, and store manager Mark Guinasso says her focus has paid off.
"Very proud of her, she did a great job," Guinasso said. "We're going to win, we're going to bring it home."
The national prize is $10,000, and Maroun doesn't have any indulgent plans for it so far for if she wins.
"I'm going to put most of it into bank accounts and forget I even have it," Maroun said.
