She focuses her practice on tort & product liability, high-stakes civil litigation, complex business disputes, and investigations. Leveraging her experience advising companies as both external and internal counsel, Anna excels in helping clients achieve their company objectives, successfully resolve disputes, and bring appropriate cases to trial.

In her tort & product liability work, Anna has represented clients in individual and consolidated litigations relating to pharmaceutical products and medical devices, and she has successfully litigated commercial claims ranging from breach of contract to complex financial disputes. Anna has practiced in state and federal courts and has represented clients in proceedings before federal agencies.

After working in private practice for more than a decade, including as a Maslon partner, Anna dedicated several years to public service as a prosecutor in the Hennepin County Attorney's Office in Minneapolis. In that role, she managed a dynamic caseload that included homicide, sexual assault, financial crimes, and drug and property cases through all stages of prosecution. She developed strong first-chair trial skills as she brought numerous violent felonies to jury verdict. She subsequently managed litigation in house as senior legal counsel for a large pharmacy benefit manager, where she oversaw a complex portfolio of litigation, arbitration, regulatory matters, internal investigations, and pre-litigation commercial disputes.

Anna received her bachelor's degree, summa cum laude, from the University of Minnesota and her law degree, cum laude, from the University of St. Thomas School of Law in Minneapolis. While in law school she served as a judicial extern to The Honorable Herbert P. Lefler of the Hennepin County District Court.
