When people or companies turn to you in a time of need and uncertainty, it is both a great honor and responsibility to assist them in solving their problems. In obtaining the best possible outcome for the client, I think creatively, address the client’s concerns and needs, and provide the best possible value to the client. The reward to the work is not only obtaining a successful outcome for the clients, but also the personal satisfaction of a well-litigated defense and victory over the adversary.”
