Mark Hammer was my husband’s attorney for nearly two years, defending him against very serious criminal charges. We were scared to death. What was going to happen? We knew my husband wasn’t guilty but would that matter? Who would listen? Who would know how the way to vindication? Mark’s being doing this work for over thirty years, as a prosecutor and criminal defense attorney and it gave us great comfort knowing that he had handled this kind of case countless times before. There were so many critical decisions that were made over the course of my husband’s case, including a dozen during the last week before trial. Mark confidently walked us through these decisions with candor and empathy. He listened to us and he directed us toward a path he’s obviously traveled many times before. In the end, I was privileged to watch an expert in his craft win my husband’s trial. Now, thanks to Mark, the nightmare is over.
