Our History

Fuss & O’Neill traces its roots to 1924 as a local survey practice founded by Hayden Griswold, Sr. Growth in the 1960s and 1970s added expertise in
land development, transportation, structures, water and sewer systems, and water resources. In 1971 the firm became Griswold & Fuss, and then
Fuss & O’Neill in the late 1970s. The early 1980s saw expansion into emerging fields of environmental compliance and permitting, and site assessment and remediation. Today the company continues to expand its expertise as engineering innovation and technological advances unfold.
