About us

MAD Scientist Associates, LLC (MAD) was established in 1998 by, Christine S. Dilley and Mark A. Dilley. As the company grew, Christine took on an increasing role in the leadership of the business, becoming CEO in 2003, while Mark has continued as Chief Scientist. MAD provides high-quality wetland and ecological consulting services to clients in the public and private sectors. Our clients include engineering firms, universities, park districts, industries, and municipal governments. Clients have come to rely on MAD for threatened and endangered species/critical habitat surveys, full wetland services (delineation, permitting, mitigation & monitoring), stream characterizations and aquatic studies, botanical surveys, ecological risk assessments, and other specialized ecological services. Our approach to life, reflected in our company name, centers on being friendly, down-to-earth, and not taking one’s self too seriously. Our approach to ecological consulting (which we take very seriously) is grounded in environmental stewardship and treating each client’s needs with the utmost respect. MAD focuses on collaboration; we want to be YOUR specialists in ecological and wetland consulting.
