He has developed sub-specialties in the areas of medical malpractice and large truck accidents.

Mr. Lyons is a member of the State Bar of Arizona (1965), United States District Court for the District of Arizona (1965), Ninth United States Circuit Court of Appeals (1971), and United States Supreme Court (1983).

He has served as a member and chairman of the Arizona Supreme Court Committee on Examinations (1974-1981); member of the Maricopa County Commission on Trial Court Appointments (1983-1987); member and Chairman of the Arizona State Bar Committee on Professionalism (1990-1991) and Client Security Fund (1990-1991); and member of the Arizona Supreme Court Special Committee to Study Civil Litigation Abuse, Cost and Delay (1990-1995).
