Thomas P. McMahon, Attorney

Tom is dedicated to making the world safe for competition, one client and case at a time. His practice is concentrated in the areas of antitrust litigation and counseling; health care, class action and other types of complex commercial litigation; and consulting and providing expert testimony with respect to attorneys fees. He has won multi million dollar lawsuits for plaintiffs and defendants at the trial and highest appellate levels of the federal and state judicial and administrative systems in Colorado and elsewhere around the country.

Tom has successfully handled virtually all types of competition-related issues under federal and state antitrust laws, including before the U.S. Supreme Court. He has extensive experience representing and advising physicians, medical groups and other health care entities regarding antitrust, competition, licensing, discipline, and privileging matters in federal, state and internal judicial and administrative proceedings. He also serves as lead, local and antitrust counsel in national, regional and state class action-type lawsuits. In other complex litigation, his experience encompasses matters as diverse as Constitutional rights under the federal Civil Rights Act; personal privacy under the federal Drivers Privacy Protection Act; government payments under the federal False Claims Act; counterfeit trade goods under the federal Lanham Act; joint operating agreements under the federal Newspaper Preservation Act; securities fraud under the 1933 and 1934 federal Securities Acts; and computer software under the Uniform Trade Secrets Act.
