04.18.11 013 EDITEDAs a firm, Duffield Associates is committed to giving back to communities in which we live and work. Our team donates to and participates in nearly 70 different local, regional, and national organizations.  We also participate in DelDot’s Adopt-A-Highway Program – which is a partnership between the Department of Transportation and volunteers, working together to make Delaware better, two miles at a time.

More than just a cleanup campaign, this innovative program works to educate citizens of all ages about the responsibilities of land stewardship-the care and repair of our environment. Ultimately, the AAH Program is about people caring enough to make a difference.

Currently Duffield Associates’ adopted highway is North Star Road in the Hockessin / Newark area.
