Hear What Our Clients Have To Say

"Kevin E. Thorn and the tax attorneys at Thorn Law Group are exceptional. When I came to them, I had just received a letter from the Department of Justice concerning an undisclosed bank account at a Swiss bank. I thought I was going to go to jail and lose everything I had worked for just because my family and my business are international. Mr. Thorn's knowledge of the tax laws and his skills in presenting my situation to the IRS and Department of Justice proved superior!"
