Chris Bentley is a former military man who turned a $10,000 personal  investment into a multi-million-dollar mineral rights firm. Less than  three years after launching Bellatorum Resources, Bentley now oversees  nearly $30 million in assets and leads a team of 16 employees. And by  the way, he accomplished it all while working toward an MBA at Rice  University, launching a charity that benefits veterans and co-founding a  nonprofit athletics school for children.
