I am an academically trained philosopher who has taught and written about medical ethics for three decades, who has done extra-mural ethics consultation in clinical and other settings for two decades, and who has served as an expert ethics witness in the courts for more than ten years. Trained as a traditional academic, none of these three pursuits have come easily. Like most philosophers, my education did not prepare me for such responsibilities. Indeed, regardless of a bioethicist's initial background - i.e., health care, law, theology or philosophy - it is invariably necessary to build upon foundational knowledges and abilities in gearing up for work as a health care ethics consultant.

Edward J. Imwinkelreid has prepared a remarkable overview of the work of the expert ethics witness from the point of view of the law of evidence. My perspective as a philosopher, an ethicist, and an expert witness, stands in contrast with his.
