If there was a way to rate less than 1 star. I would. I have never been compelled to write a review in my life. Unfortunately people should be warned this man, is the most unprofessional, rude, and snide lawyer I have ever met.

While being infront of the judge, constantly argues with you, and if you want him to do what he was hired and paid upfront to do, if he doesn't agree with you, will threaten to drop you as a client mid-discussion. He will fight more for the opposing party than you. The fact that he continues to post peoples personal case notes, to public forum, should show how petty and low this man is. Which, i do believe is against the regulations for lawyers either way.
