I contacted Bill Sullivan when I received a settlement demand letter and he jumped to action to get answers and help me figure out which direction I needed to head in. While I ultimately didn't become a client of his, I was impressed with his professionalism, transparency, and honesty. He held himself to his word and went above and beyond to help me make the choice that would be best for my situation. Thank you, Bill!
