Gregory E. Heltzer


Gregory (Greg) Heltzer analyzes the antitrust implications of most transactions involving a publicly traded company – including over 800 in the last decade. Greg focuses his practice on defending mergers and acquisitions and has successfully defended mergers for DaVita, Mars, Martin Marietta Materials, Olam, TreeHouse Foods, Motorola Solutions, Le Duff America, JAB Partners (Coty), Aleris, and Blackboard among others. His advice allows C-Suite decision makers to ensure that time and money are not wasted on potential transactions without a viable path for clearance. When transactions move forward, Greg guides clients through the clearance process with a focus on providing enforcers with the information needed so that the merging parties can avoid or at the very least significantly reduce the scope of a costly/time-consuming Second Request. In addition, he handles complex antitrust litigation, government investigations and antitrust counseling. Greg has experience in all three branches of government. Prior to joining the Firm, he served as a judicial law clerk for the Honorable John A. Terry of the DC Court of Appeals. Before entering law school, Greg worked for the US Environmental Protection Agency in the Energy Star Program. He also served as a legislative intern on the staff of the US Senate Committee on Environment and Public Works under the late Senator John Chafee (R-RI). While in law school, Greg was a member of The Tax Lawyer. Greg also founded McDermott’s Antitrust Alert blog and continues as its managing editor.
