About me

I am an aggressive trial lawyer who will fight for your rights.  I am also an experienced negotiator who will work to obtain the best offer.  I have represented clients law all over the world as an Army Judge Avocate (JAG) and am a committed fighter.  I have represented military members in all branches of the service.  While on active duty I tried over 30 courts-martial.  Essentially, I am a very experienced litigator and have litigated and won many jury trials.  My years of experience make me qualified to represent you in all areas of the law and I love a challenge.  When you hire me you get professionalism, courage and commitment.
