Prior to entering law school, Mary Ellen worked as a chemical engineer for the Environmental Protection Agency in Superfund emergency response/site characterization and Resource Conservation and Recovery Act (RCRA) incinerator permitting, and then as an environmental project officer for a commercial hazardous waste incineration company overseeing RCRA, Toxic Substances Control Act and Clean Air Act permitting and compliance. During law school, she worked as a law clerk for the EPA Office of General Counsel Air and Radiation Division.

Since its debut in 2004, the International Who's Who of Environment Lawyers has named Mary Ellen to its prestigious list of pre-eminent environmental lawyers worldwide each year. Her achievements in the area of environmental law have also earned her inclusion in The Best Lawyers in America.

In 2007, her comprehensive publication entitled "Basic Practical in Nanotechnology" won a competitive, peer reviewed "Best Paper Award" at the American Bar Association's Section of Environment, Energy and Resources fall meeting.

In 2008, Mary Ellen was granted early election as a fellow of the American College of Environmental Lawyers, a professional association of private sector environmental lawyers recognized by their peers as pre-eminent in their field.

Recently, Mary Ellen accepted nomination for the role of Master Programming Chair for the American Institute of Chemical Engineers 2010 Spring National Meeting which will provide engineering, environmental and energy educational programming for several thousand industry engineers.
