For four decades, Rick has been at the forefront of antitrust law and is uniquely capable of advising clients on the antitrust regulatory environment affecting the way they do business globally. As agencies and rules have evolved, he has helped clients to understand the dynamic legal framework, to assess the legal risk and rewards associated with a range of competitive strategies, and to work with government bodies to take advantage of, and ensure appropriate compliance with, the regulations governing the clients’ chosen strategy.
