A relentless competitor, Mark Wallin’s practice is focused on defending businesses in complex class, collective, and multi-plaintiff actions, involving a wide array of employment and commercial disputes. His ability to understand complex class litigation as well as his clients’ practical concerns allows him to look ahead to provide strategic advice for resolving sophisticated issues – whether through adjudication or negotiated resolution.
Mark has been lead counsel in a variety of class and collective action matters involving breaches of contract, breaches of fiduciary duties, as well as violations of the FCRA, FLSA and state wage and hour law, including class and PAGA actions brought under the California Labor Code. Through tenacious advocacy, Mark has defeated FLSA conditional collective certification and Rule 23 class certification because he understands what strategic and tactical steps are necessary to mitigate or avoid such representative treatment and the often-substantial liability that can flow from it. He has also represented businesses in multi-plaintiff and single-plaintiff discrimination litigation.
Mark strives to provide the highest-level of service to his clients, guiding them through every step of the process and building long-term relationships. Mark believes it is his role to understand his clients’ business needs so he can help them determine what a “win” means to them. Indeed, Mark has successfully represented companies of virtually all sizes, from Fortune 500 to family owned small businesses.
Mark has also undertaken several pro bono cases, including trying criminal jury trials in state and federal court and representing indigent plaintiffs in civil rights matters as part of the Trial Bar for the United States District Court for the Northern District of Illinois.
Mark began honing his litigation skills during law school while working at the U.S. Attorney’s Office for the Northern District of Illinois, where he worked on civil and criminal issues. Also during law school, he worked for judge on the U.S. Court of Appeals for the Seventh Circuit, which gave him a unique vantage of seeing the issues from the court’s perspective.
