 99.7 WPRO.com. Dan owed an unbelievable amount of money to the IRS. I got behind on my taxes. It's a horrible feeling. He was in denial. When I got those letters from the IRS, he wanted to act like they didn't exist. Finally, Dan turned to Optima Tax Relief, the leading tax resolution firm. A-plus rated by the Better Business Bureau, they've resolved over $1 billion for their clients.
