John Williamson is exceptionally smart, hard-working and talented. No one will out lawyer John as he has that rare combination of big law experience at the highest level, real trial experience and an exceptional strategic mind. His ability to connect to clients and juries makes him a formidable adversary. And his Southern charm is not only the perfect complement to his determination, it is who he is.
