Gaye Sprague – owner, principal

With 40 years of experience in the field of traffic engineering and transportation planning, you could say Gaye knows how to keep people moving. She has worked for both city and county governments, as well as two consulting firms besides her own.

A strong practitioner and believer in civic leadership, Gaye served on the South Carolina Board of Registration for Professional Engineers and Land Surveyors from 2002 to 2008 and in the Greenville community has served as chair of the Board of the Greenville Transit Authority and the Greenville Chamber of Commerce Transportation Committee. Gaye is active in the Institute of Transportation Engineers (ITE) and has served in all offices in the South Carolina Section and Southern District as well as on the International Board of Directors. She is also a member of the American Society of Civil Engineers and the National Society of Professional Engineers (NSPE) and was named 2006 Engineer of the Year for the Piedmont Chapter of NSPE.

In 2017 the SC section ITE honored Gaye by co-naming an annual scholarship in her honor. In addition to her professional life, Gaye has a history of deep involvement in numerous local non-profit and civic organizations, and she served as one of two at-large representatives on Greenville City Council from 2009 to 2017.
