Creighton Manning began providing professional services in 1965 under the direction of Roger L. Creighton and Charles W. Manning, P.E. Based in Albany, NY area, Roger and Chuck were pioneers in the transportation industry, having led major urban area transportation studies in Chicago and upstate New York. Roger authored a textbook on urban transportation planning in 1970 and later worked with Chuck to revolutionize the analysis of complex transportation problems by developing innovative software programs for use on the then state-of-the-art micro computers in the mid to late 1980s.

Since the 1990s, under the vision and guidance of co-owners John M. Tozzi, P.E., and Edward V. Woods, P.E., Creighton Manning has grown into a multidisciplinary engineering and planning firm providing professional services to the transportation, municipal, land development, and energy markets. The firm continued to grow in the 2010s by adding new partners and opening additional offices across New York State.
