He sold his family's West Virginia coal operations to Russia's Mechel OAO for $436 million in cash in 2009. Justice also received about $240 million in Mechel stock, which he has since sold.
That same year, he purchased the bankrupt Greenbrier resort from CSX for $20 million, with the aim of returning the world-class resort to profitability.
He has since invested more than $200 million in the hotel, building a brand new casino and establishing the Greenbrier Classic golf tournament and concert series.
Combined with his investment in the Greenbrier's medical facility, Justice's improvements at the White Sulphur Springs resort have topped $400 million.
"To get The Greenbrier into a profitable stage has been very, very difficult," he said.
Justice had to lay off about 100 of the 1,800 staff members at the resort last January due to a decline in winter business.
He said business did get somewhat better over the last year.
"It's surely not what I would call extraordinarily," he said. "I mean this economy is tough on any kind of business."
Justice said he believes The Greenbrier will return to profitability soon.
"I think we've turned the corner at The Greenbrier," Justice said. "We've done a lot of work and invested a lot of money. We haven't completely turned it, but we can see the light that we've got better days ahead."
Meanwhile, Justice's immediate focus is on coaching tonight's AAA regional co-final boy's basketball game between his Greenbrier East Spartans and the South Charleston Black Eagles.
Despite his growing fortune, Justice still coaches the high school's boys and girls basketball teams.
"I want to do the right stuff - I just do," Justice said. "I want to try and help as many people as I can.
"I believe the Good Lord tells me every day, 'This is what you're supposed to do,' and I don't take that lightly," he said.
