Susan E. O’Rourke, P.E.

President/Traffic Engineer

Ms. O’Rourke began her career in 1985 as a traffic engineer in West Palm Beach, Florida. Her unique mix of public sector policy development and private sector implementation have provided the insight to bring complex project through the approval process. A graduate of Vanderbilt University, Ms. O’Rourke has managed projects in all areas to include large scale traffic studies, policy development, parking studies, transit analysis, mobility analysis and transportation design. Ms. O’Rourke likes a challenge. When she is not at work she enjoys running and serving on committees.

2020 has been a big year in the O’Rourke household. Sons Keegan and Bob are graduating from college and high school, respectively. Both have served their time over the years working in the office, counting cars in the field or helping with “IT” issues, CAD design, and complex spreadsheets. Keegan will be moving on to a position as an electrical engineer and Bob is headed to the Naval Academy Prep School. Ms. O’Rourke is thankful that her son Taylor can give us some continued service as the Covid virus caused a reduction in hours in the New Jersey lab where he is currently employed.
