Kristin Zinsmaster helps companies of all kinds successfully navigate complex criminal and civil litigation, enforcement actions, and investigations. She has worked on matters at every stage — from internal investigation to discovery to jury trial — in state and federal courts.

Kristin assists clients in many and varied industries, with particular focus on those doing business in the areas of health care and financial services. Her experience in litigation and investigations encompasses a range of subject areas, including business torts and contract disputes, fraud and embezzlement, federal securities law, shareholder derivative actions, anticorruption (FCPA and U.K. Bribery Act), and the False Claims Act.

Prior to joining Jones Day in 2016, Kristin practiced law at another firm in Minneapolis. During this time she participated in the investigation and litigation of securities and shareholder derivative matters in state and federal courts for a large medical device manufacturer. The majority of these matters resulted in unequivocal victories. Through this work, Kristin gained extensive experience in special litigation committee (SLC) investigations. She also devoted a significant portion of her practice to assisting clients in the financial services industry, defending against SEC and FINRA inquiries and an enforcement action brought by the United States Commodities Futures Trading Commission.

Kristin maintains a sizeable pro bono practice, devoted primarily to representing defendants in the District of Minnesota who qualify for the services of the Federal Defender. Kristin is a former collegiate athlete and serves on the board of directors of CycleHealth, an organization devoted to kids' wellness.
