Don’s practice is concentrated in antitrust/trade regulation law, agricultural cooperative law, trade association representation, and complex antitrust and commercial litigation. He has defended numerous antitrust claims including major, multi-district litigation and class actions. Don has represented clients in the defense, entertainment, high technology, health care and agricultural sectors, including agricultural cooperatives, defense contractors, physician groups, trade associations and companies in the software, construction and soft drink industries. Don co-chairs the Antitrust Competition Law Practice Group.

Given the diversity of this client base, Don has developed subspecialties in criminal antitrust, health care antitrust, agricultural cooperative law, mergers and acquisitions, and administrative law. Don has served as general counsel for a major trade association in the entertainment industry. He has also represented trade associations in commercial and antitrust litigation and has assisted them in standard-setting activities, anti-counterfeit and anti-gray market enforcement programs, mergers and acquisitions, and trade show disputes.

Over the past four decades, Don has developed particular experience in agricultural cooperative law with special emphasis on the applicability and reach of the Capper-Volstead antitrust exemption. In addition to defending cooperative antitrust litigation, he routinely assists cooperatives in structuring innovative and antitrust-compliant business models to expand value-added marketing opportunities and increase member returns. In federal courts, Don has also challenged various rulemaking proceedings of the United States Department of Agriculture as arbitrary and capricious under the Administrative Procedure Act.
