Attorney Andrea Bierstein is a partner at Simmons Hanly Conroy. With over three decades of legal experience, Andrea is one of the premier appellate brief writers and oral advocates in the nation. She works in the Complex Litigation Department and has secured millions of dollars on behalf of her clients, including a $32 million antitrust settlement for a medical supply manufacturer.

“I strive to hold negligent corporations accountable and recover compensation for those who have been harmed by their actions,” said Andrea.

Andrea is highly experienced in all forms of civil litigation and is a former law professor at Western New England College School of Law in Springfield, Mass. There, she designed and taught an annual civil litigation clinic and second-year law courses in Evidence and Remedies.

Andrea excels in appellate work and law and motion practice, having won multiple cases on appeal, and is known for writing persuasive legal briefs and providing clear legal analysis. Lawyers from other firms frequently seek her out to work on complex briefing projects or to assist or edit their own work.

Currently, she focuses her legal practice on opioid litigation, consumer protection class actions, commercial litigation, and environmental law. She works out of the firm’s New York office and resides in New York City.


Andrea attended Princeton University for undergrad, majoring in history. She earned her J.D. (cum laude) from New York University in 1984. She is admitted to practice in nearly a dozen courts throughout the country including New York, Massachusetts and the U.S. Court of Appeals in the Second, Seventh, Ninth and Eleventh circuits.

Andrea has been included in the New York Metro Super Lawyers roster every year since 2007.
