  • Christopher Daniel Leroi

    Mr. O'Steen is an exemplary attorney who I would recommend to everyone and anyone. Hiring him might very well be the best decision that you have ever made. His answers on Avvo are perfect. I have practiced for 24 years as a judge, magistrate, prosecutor, and private attorney and he is one of the best I have encountered.
