"John and I were opposing counsel in a divorce that dealt with some highly sensitive issues. Our clients approached the divorce in a civil manner. However the divorce dealt with some highly delicate issues that, with a lesser lawyer, could have turned into a fought out divorce. Together, we managed to negotiate the issues and provide our clients with the civilized divorce they deserved. I credit John for keeping matters calm and steering the case away from litigation and moving it toward settlement."
