Practice/Organization Description

I am Co-chair of the Firm's Antitrust/Competition Practice Group and represent clients in a wide variety of industries. My experience over 25 years of practice, including service in senior positions with the Department of Justice Antitrust Division, make me an effective problem solver.

The principal focus of my practice is representing clients in the antitrust aspects of mergers, acquisitions, joint ventures and other business combinations. Working closely with corporate counsel, and applying my detailed knowledge of Hart-Scott-Rodino (HSR) regulations, I take an active role in structuring business combinations to avoid antitrust problems. I have acted as lead counsel in scores of transactions representing clients in investigations conducted by DOJ, FTC, and state attorneys general. I also have designed and implemented a number of antitrust compliance programs relating to a broad range of issues including advertising, pricing, information exchange and distribution practices. Where necessary, I have litigated on behalf of clients in administrative proceedings and in federal court.

Currently I am representing Dean Foods in the first merger challenge brought by the DOJ in the Obama administration, as well as in unrelated class action litigation in Tennessee and Vermont. Earlier I represented Whole Foods Market, Inc. in fighting off the effort of the Federal Trade Commission to enjoin Whole Foods Market's acquisition of Wild Oats Market and in related administrative litigation.
