I have worked with Matt for a number of years. Last Wednesday, we won a 3-week trial in our 10 year old case. He is an incredibly smart, talented and sophisticated trial lawyer. Most important to me, he is of impeccable integrity and conducts himself with the utmost professionalism. He is a master of strategy, nuance, witness examination – direct and cross – arguing motions, flexible and nimble as required during a long, difficult trial, witness preparation, and client relations. The icing on the cake was Matt’s masterful closing argument. Throughout his closing, the jury was riveted and I kept thinking how he nailed each and every point and argument, picturing in my mind Simone Biles nailing her Olympic vaults with pinpoint landings time and time again. It was beautiful and a true pleasure to witness.
