I highly recommend Attorney Gregory Erchull. I have known and worked with him as a colleague for over seven years. He is one of the best negotiators I have ever worked with. Few know that he learned that skill as a lineman playing semi-pro football. He learned with a steely eyed patience that the next person who moved on the line lost. In negotiation he knows that when an offer is made, the next person who talks loses. That is the most important rule in negotiation. Few attorneys other than Greg Erchull have mastered that rule.
-Attorney Jerome Krings
