Legal Medicine Expert Witnesses: 5

• Increased quality and integrity of written expert reports, based on an expanded knowledge base

• Since there is so much overlap between fields in the medical profession it is often hard to determine where one scope ends and another begins. This ambiguity is dramatically decreased , and scope increased by combining physician, pharmacist, and pharmacologist into one
• Communication skills of a pharmacist and experience dealing directly with the lay-public, in addition to the knowledge and background of a physician is extremely beneficial describing technical details to a jury
