In high school, Louis Russo’s mother was diagnosed with ovarian cancer and given a somber prognosis. But given the gift of time she lived another ten years, and it was in those years that Louis recognized the unique and novel innovations of the pharmaceutical industry is what extended her life, driving his passion to become the lawyer he is today. Louis enjoys the rigor of law, the opportunity that each case offers to dial in on a new subject or industry, and the challenge of digging deep into science to master new concepts. Louis believes continual learning is the difference between a good lawyer and a great lawyer.

As a member of the firm’s Complex Litigation, Pharmaceutical Products, and Toxic Torts & Products Liability groups, and a member of the firm’s trial team engaged in the serial litigation over an EPA-approved herbicide, Louis represents clients in a variety of litigation matters focusing on products liability and complex litigation defense. He has significant experience in all aspects of products liability litigation, including fact and expert discovery, proceedings before the Federal Judicial Panel on Multidistrict Litigation, pleading and summary judgment motions, Daubert/Frye motions, trials, appeals, and settlement strategy.

Prior to joining Hollingsworth LLP, Louis served as an associate for a nationally ranked New York law firm and credits the following to his background of experience:

  • Defended major pharmaceutical and medical device manufacturers in products liability matters involving antibiotics, antipsychotics, carbonic anhydrase inhibitors, prescription opioids, surgical mesh, and suture anchors;
  • Defended a major consumer goods manufacturer in a state consolidated litigation involving cosmetic talcum powder, leading fact discovery and depositions. In that same litigation, he was a member of the trial team for the first New York trial involving the cosmetic talc product, preparing motions in limine, evidentiary motions, post-trial briefing, and appellate briefing, which resulted in dismissal of all claims;
  • Represented clients in complex commercial litigation in areas including anti-counterfeiting, antitrust, tort, contract, and business organization law;
  • Represented pro bono clients in appeals involving criminal law, administrative law, domestic violence, and human rights abuses.

Louis received his J.D., magna cum laude, from Fordham University School of Law where he was elected to the Order of the Coif and served as Senior Articles Editor of the Fordham Law Review. He graduated summa cum laude from Wagner College with a B.A. in Government/Politics and Economics.

When he’s not peeling back the layers of science, Louis is a dog lover and can be found doing just about anything with his dog, Riley, including boating and hiking.
