“Highly articulate, intelligent, practical and knowledgeable—he is a well-rounded lawyer and aggressive litigator.”
- John Skoutelas, VP, Legal Affairs Northeast United States, Waste Management

Partner Robb Fox has a diverse practice involving compliance counseling, litigation and transactional work for clients in the waste, chemical manufacturing and development industries and on behalf of cities and municipalities.  He is known nationally for his work under the federal Superfund law including handling many high-profile Superfund matters such as the Keystone Landfill matter, featured on 60 Minutes, and the Gowanus Canal and Newtown Creek sites.  He regularly litigates Superfund issues of first impression at the trial and appellate levels in multiple jurisdictions. 

Robb’s litigation experience extends to superfund cost recovery, class action and toxic tort defense, trials and appeals before federal and state courts and administrative tribunals.  He also represents local, regional and national clients in the environmental aspects of business transactions, ranging from redeveloping brownfields (he assisted in the drafting of the 2002 brownfields amendment to the federal Superfund law) to managing liabilities in the environmental acquisition and divestiture of multinational companies.

Robb was the firm's Managing Partner from 2007-2014. He was listed as "Philadelphia Area Best Lawyers Environmental Lawyer of the Year" (environmental law), 2019 and 2010; and "Philadelphia Area Best Lawyers Environmental Lawyer of the Year" (environmental litigation), 2012*.

Robb’s personal interests are as diverse as his law practice.  He is a competitive tennis player, a devoted Phillies fan and loves cooking.  In 2012 he was named Top Chef in a competition among Philadelphia lawyers.  He is married to his high school sweetheart and has two daughters and three grandchildren.
