What started as R.H. ERICHSEN, CIVIL ENGINEERING in the basement of Roy Erichsen’s home in 1952 rapidly grew to become HGE with the addition of architects Bruce Harlan and Richard Gessford. The three professionals, whose initials gave HGE its name, provided architectural, engineering, and surveying services to the community for many decades. The company’s size continued to ebb and flow over the years, at one point boasting 30 employees and a second office in Portland.
