Mark R. Thierman is Founding Partner at Thierman Buck. Mark is one of the pioneers of wage and hour class actions nationwide. A 1976 graduate of the Harvard Law School, Mark has been an employment lawyer for four decades and involved in more than 100 reported cases nationwide. Early in his career, Mark exclusively represented employers and management with their labor and employment concerns. However, he changed focus to working on behalf of employees who were not being represented in wage disputes. Mark has obtained settlements and judgments amounting to close to a billion dollars in unpaid wages, overtime pay, and benefits on behalf of employees.

Mark’s innovative and no-nonsense approach to addressing labor and employment violations has landed him on the cover of numerous magazines and as a guest on TV and radio shows across the nation. In 2007, Mark was featured as the cover story of a BusinessWeek magazine article entitled “Wage Wars.” This piece focused on the trend of applying “old” labor laws to new professions, and highlighted many of Mark’s new and innovative cases on behalf of employees who were denied proper compensation for all the hours worked. The article stated that Mark “pursues a practice that in recent years has won his clients hundreds of millions of dollars from some of the biggest names in Corporate America.” Despite the article’s innuendo, Mark is not a cowboy; he doesn’t carry a gun; and he’s not originally from Nevada. 

In 2014, Mark argued the case of Integrity Staffing Solutions v. Busk before the Supreme Court of the United States, with Partner Joshua Buck at his side. The case raised several important labor issues that affect workers across the nation. The federal portion of the case was overturned on one point by the Supreme Court, the decision clarified important aspects of employment  law. Nevertheless, the state law claims remain viable means for workers in numerous states to recover unpaid wages owed.

Mark remains an innovator in his effort to protect working people of all stripes; he’s never afraid to challenge the unknown; and he’s always up to take on new, intriguing, and difficult cases on behalf of his clients.
