Dr. Joseph Regna

A graduate of Boston University School of Medicine and Johns Hopkins University School of Hygiene and Public Health, Joseph Regna has applied his knowledge and training as a medical toxicologist and a specialist in environmental and occupational health. In his professional capacity, he has partnered with a range of stakeholders, including consulting firms, small businesses, attorneys, individuals, and community organizations. Central to this work has been the assessment of the effects on human health from exposure to hazardous substances. In his role as an expert witness, Joseph has honed his skills in explaining complex concepts in terms that area understandable to non-experts. Dr. Regna’s interests include natural history, nature, and exploration; music enjoyment and appreciation; and classic cars of the 1950s and 1960s. An owner of two automobiles from the latter decade, one of which was his first car, Dr. Regna has participated in the filming of motion pictures produced in the Boston area, both with his cars and as background.
