The Origin of the Roundtable of Toxicology Consultants

Dr. Richard Parent founded the Roundtable of Toxicology Consultants (RTC) in 1986 following ongoing discussions with active toxicology consultants at Society of Toxicology meetings dating from 1984.  Since that time the RTC has become the oldest and largest organization of independent consulting toxicologists in the world.  Over the years he has actively and graciously  helped many toxicologists make a successful transition from industry, government or academic careers in toxicology to success as independent consulting toxicologists who each day make significant contributions toward advancing the practice of toxicology in many unsung practical ways.

Not surprisingly, the early history of the RTC, from 1984 through 1988 was a formative time.
