“My clients are health care professionals who have literally dedicated their lives to helping the sick and injured, to bringing new life into the world, and to preserving the health and well-being of those they care for. To be charged with negligently causing harm to a patient is one of the most unsettling events of their professional and personal lives. My goal is to guide my clients through the unfamiliar territory of medical malpractice litigation while preserving their dedication and service to their profession, and also sharing my belief that our legal system does produce justice.”
