Mark Humenik is a fierce advocate for employees and talented professionals. He represents employees, executives, and business entities in prosecuting labor and employment litigation, complex commercial litigation, and specialty tort actions. He also specializes in representing professional athletes, coaches, and media personalities in contract negotiations and employment-related disputes. During his two-decade professional career, Mark has been instrumental in securing contracts collectively worth more than $1 billion in value for his clients.

Mark recently expanded HPK’s litigation practice into California and heads the firm’s Southern California office in Orange County. Before joining HPK, Mark was Executive Vice President and General Counsel at Athletes First, where he represented many high-profile professional athletes, coaches, and celebrities, while also handling all of the sports agency’s legal matters. Mark spearheaded the sports agency’s successful litigation of a complex, multimillion dollar “bet your business” dispute that was favorably decided by the United States Court of Appeals for the Ninth Circuit in Steinberg Moorad & Dunn v. Dunn, et. al. He later managed and supervised the firm’s sale of a minority equity stake in the sports agency to strategic investor and Japanese advertising conglomerate, Dentsu Inc., for $16.5 million. Mark also secured the largest arbitration award in the history of the National Football League Players Association in a multimillion dollar fee dispute between NFLPA contract advisors.
