"An incredible antitrust lawyer.” So says one of Mark’s clients or peers, according to the legal ranking organization, Chambers USA. In today’s vernacular, that’s about as high a compliment as one can get.
A little more than twenty years ago, Mark left the Federal Trade Commission and joined Womble Bond Dickinson. At that time, Womble had no antitrust practice in the healthcare sector; Mark essentially started one from scratch. Today, he represents most of the national health systems and many regional health systems in a variety of capacities. Mark regularly appears before federal and state antitrust enforcement agencies in securing clearance for mergers, joint ventures and other transactions. He has also served as counsel for health systems throughout the country in antitrust litigation involving managed care contracting, medical staff privileges, economic credentialing, physician recruitment practices, nurse salary determinations, and exclusive provider arrangements.
Mark served as the Chair of the North Carolina Bar Association Antitrust Section in 2001 and 2002. He has also held numerous leadership positions within the Antitrust Section of the American Bar Association and received recognition for his contributions to ABA publications on antitrust issues in healthcare.
- Between 1989 and 1995, Mr. Horoschak served as Assistant Director of the Bureau of Competition of the Federal Trade Commission. In that capacity, he was responsible for antitrust enforcement policy governing healthcare provider systems and served as trial counsel in two lawsuits that successfully challenged hospital mergers. Prior to that position, Mark served as an attorney advisor for the Chairman of the Federal Trade Commission and as chief-of-staff for the agency during the transition between the Reagan and Bush administrations.
