Mr. Joseph’s clients originate from a broad spectrum of industries, including: health care; pharmaceutical and medical device; securities, insurance and financial services; food services; and manufacturing. He has also been qualified and has served as an expert consultant and trial witness in high-stakes litigation that requires expert testimony regarding how law enforcement perceive and act upon allegations of fraud, whistleblower retaliation, and other civil and criminal violations.
