about MarkX+X+

Making a career out of protecting consumers, Mark is relentless, laser-focused on details, highly creative, and ready to serve at a moment’s notice.

As the co-leader of the firm’s class action efforts on behalf of plaintiffs across the country, Mark often takes on some of the world’s largest and most sophisticated companies. After spending the beginning part of his career doing defense work, Mark is dedicated to vindicating the rights of consumers against corporate misdeeds. His work takes him across the country, practicing in state courts across Ohio and federal courts from California to Virginia. Such a practice relies on relationships with other lawyers nationwide, which is essential when taking on adversaries who are sophisticated and are not afraid to use their vast resources to defend themselves. As a co-author of the leading guide on Ohio Consumer law for nearly a decade, Mark has kept up with the emerging trends in consumer law, enabling him to assume leadership roles in the cases he works and helping his team to think ahead on the impact of certain decisions they make and how they influence the final result. Mark’s representative cases include, but are not limited to, the following:
  • Lead Counsel in Consumer Class Action against Porsche in which the parties settled the plaintiffs’ claims for tens of millions of dollars
  • Special Counsel for the Ohio Attorney General in claims against five of the country’s largest pharmaceutical companies alleging misrepresentations and deceptive marketing that caused the nation’s current opioid crisis
  • Lead Counsel in Consumer Class Action against Global Fitness gyms that operated under the name Urban Active, which eventually settled for amounts equivalent to several months’ gym dues
  • Lead Counsel in Consumer Class Action against Ford Motor Company alleging vehicle defects leading to unintended acceleration
  • Liaison Counsel in Consumer Class Action against Honda alleging undue vibration in their 2015 and 2016 Honda CR-V model vehicles
