Erin Brockovich is an American paralegal, consumer advocate, and environmental activist who was instrumental in building a case against Pacific Gas & Electric Company (PG&E) involving groundwater contamination in Hinkley, California for attorney Ed Masry in 1993. Their successful lawsuit was the subject of the Oscar-winning film, Erin Brockovich (2000), starring Julia Roberts as Brockovich and Albert Finney as Masry.

A paralegal, also known as a legal assistant, or paralegal specialist is a legal professional who performs tasks that require knowledge of legal concepts but not the full expertise of a lawyer with an admission to practice law. The market for paralegals is broad, including consultancies, companies that have legal departments or that perform legislative and regulatory compliance activities in areas such as environment, labor, intellectual property, zoning, and tax. Legal offices and public bodies also have many paralegals in support activities using other titles outside of the standard titles used in the profession. There is a diverse array of work experiences attainable within the paralegal field, ranging between internship, entry-level, associate, junior, mid-senior, and senior level positions.
