The firm we know today as ARCADIS began in the late 1800's as Nederlandsche Heidemaatschappij in the Netherlands to increase the productivity of the land. By the mid-1950s, when Geraghty and Miller was founded, our country's demands on its natural resources were mounting as Americans looked to grow in virtually all areas. In the face of increasing environmental and infrastructure needs and with the support of our clients, the firm continued to grow and expand its capabilities merging with trusted firms in the industry. We continue to expand our role as a world-class institution with nationwide and global capabilities in developing and implementing solutions for the built and natural environment.
