I am only in the beginning stages of a case...I have full confidence in Mr. Duffy...he is undeniably well rounded. He always has an answer and has that hunger for finding justice for his clients..

I learned that I must pursue the judiciary committee in the House of Representatives to seek the impeachment of federal judges.
He was not a jerk as most lawyers. He actually talked to me and gave me free legal advice. I literally thanked him for not being a jerk. My only disappointment was that, overall, I knew more federal rules of civil procedure and constitutional law than he did.
