Andrea E. Sewall
Andrea Sewall, the leader of CDM Smith’s environmental services group, has spent four decades with the firm. Her team helps public and private clients conduct remedial investigations and feasibility studies, as well as overseeing risk assessments and site cleanup activities related to contaminated land, groundwater, buildings, and infrastructure.
“I am passionate about the power that strong diverse teams bring to solving the most difficult problems,” she says. “The world’s greatest technical institutions are founded on the concept of bringing many minds and talents together to create new ways of thinking and new ideas for delivering projects efficiently and effectively for our clients.”
Andrea has chosen to build her professional career at CDM Smith because “We are the best in the industry. We are highly dedicated to our clients and our staff, and we care deeply about technical excellence, teamwork, and integrity in all that we do to make the world a better place.”


I believe that strong teams are at the heart of technical excellence, quality and innovation.
