Greenberg Traurig LLP

Work Department



David G. Mandelbaum is co-chair of the firm's Environmental Practice. He represents clients faced with problems under the environmental laws that have no conventional solution, or for which the conventional solution would yield an unacceptable result. While he regularly represents clients in lawsuits, he does not restrict his practice to litigation and has helped clients achieve satisfactory outcomes through regulatory negotiation or private transactions. David handles some of the most significant Superfund and hazardous waste litigation in the United States, and he represents natural gas exploration and production companies, midstream providers, and landowner coalitions in connection with development of the Marcellus Shale and other natural gas resources. He regularly handles permit appeals and citizen suits under the water pollution, air pollution, and solid waste laws. He has represented clients in litigation under the National Environmental Policy Act (NEPA) and several disputes among private parties following failed or unsatisfactory transactions.
