"Egan, Field & Nowak, Inc. (EFN) tradition of excellence began in 1872 with J.E. Egan’s first office near the banks of the Mississippi River. Each passing decade has strengthened our foundation as one of the largest and most respected surveying firms in the upper Midwest. Having over 151 years of roots in the industry, we offer an unparalleled wealth of records, experience and knowledge to our valued clients in the public and private sectors of land surveying, energy and civil engineering. Today, our approach to quality is the same as it was in 1872, but we now employ the latest technologies to achieve that goal."
