About me

I believe that  my purpose  as a  lawyer is to not only represent you to the fullest of my abilities but also to explain and counsel you on what has happened to you and what will happen to you.  You can have all the legal knowledge in the world but you are useless if you cannot effectively talk to people and make them feel comfortable and at ease.
