 Trustindex verifies that the original source of the review is Google. Allen represented me in an accident case in which he did a fantastic job. First of all he gave me more money off of the total than he was required to. In the beginning of a criminal defense case, that he is also handling for me, he worked with me on the fees and was way more than patient. Can’t say enough good things about him as a professional and a person with integrity. Y’all, hire him! Highly recommended!
