It was the first and currently the only meeting Howard, an Atlanta native, has scheduled.
"It was a really, really, really good meeting," the source said. "Very impressive. Dwight's going to look at all his options. But it went very, very well."
Howard, who has also drawn interest from Boston, is scheduled to speak with other teams by phone Friday, the source said.
He hopes to make a decision within the next day or so.
ESPN.com's Calvin Watkins reported that Howard is looking for a contract beginning at $24 million per year. But the source would not confirm that.
"The market is going to set itself," he said. "Dwight is focused on winning."
Howard had planned to hold meetings in Las Vegas on Saturday, but those plans were changed. Instead he'll remain in Atlanta.
