Mark represents a wide variety of clients in complex litigation, including both public and private companies, as well as small businesses and individuals. His litigation experience encompasses an array of commercial litigation matters, including defending clients in cases involving breach of contract, trade secret infringement, and other business disputes. Knowing that these disputes often involve industry-specific issues, he works closely with clients to gain a full understanding of their business and operations before determining a litigation strategy.

His practice also extends into other areas of litigation, including construction disputes and personal injury matters, where he has represented both plaintiffs and defendants in traumatic brain injury cases. Additionally, Mark represents municipalities and government entities, schools, educators, and attorneys in disciplinary proceedings. He has tried cases to judges and juries, and he has argued before the U.S. Court of Appeals for the Sixth Circuit, as well as the Ohio First and Second District Court of Appeals.
