A former Attorney General of Maryland and president of the National Association of Attorneys General, Doug draws on more than 30 years of public advocacy and leadership in advising businesses and individuals facing federal and state investigations and enforcement actions, as well as civil and criminal matters involving state Attorneys General, the Department of Justice and other government agencies. Doug is viewed as a problem-solver and successfully handles a broad array of general civil and criminal litigation matters.

Doug represents clients in responding to and, when necessary, defending against AG inquiries from across the country, whether in civil lawsuits, regulatory investigations or both in matters involving financial services, health care, pharmaceutical, insurance, telecommunications and other consumer industries.

Doug was appointed by the Pennsylvania Attorney General as Special Deputy Attorney General to investigate the improper use of email by Pennsylvania state employees, and he has conducted internal investigations for numerous national corporations. Throughout his career, Doug has handled a range of civil and criminal cases involving public corruption, economic crimes and other issues, including:

In the public sector, Doug’s record of leadership includes:
