Justin's practice is focused on obtaining favorable results in matters arising from alleged violations of state and federal laws, including fraud, the Foreign Corrupt Practices Act (FCPA), the False Claims Act (FCA), and the Food, Drug & Cosmetic Act (FDCA). He has successfully tried numerous cases in state and federal courts throughout his two decades in public service and private practice.
Since rejoining Jones Day in 2021, Justin has provided advice and counsel to a variety of clients in diverse industries such as health care, manufacturing, finance, professional services, and higher education. Justin is frequently retained by clients in high-profile matters requiring a careful balance of legal strategy and conflict resolution.

Justin also maintains an active pro bono practice. In 2022, his trial work with the Ohio Innocence Project led to the acquittal of a wrongfully convicted man who had spent 15 years in state prison.
