Spencer Gilligan Recommendation
I have followed Spencer' career from the time he was in law school. His trial skills and ability to communicate with the Court and jury are exceptional, and his integrity is rock solid. When you need legal assistance, there is no one I would recommend more highly. I have placed my family's well being in his hands, and I have never made a better decision.
