July 2010 – TWM ranks as the 13th largest engineering firm in the St. Louis region according to the St. Louis Business Journal’s 2010 list. The firm has been on the list eight years, steadily moving up from No. 24 where it first appeared. The business journal bases its rankings on the number of licensed engineers the firm employs in the City of St. Louis and 11 surrounding Illinois and Missouri counties.

In addition to the St. Louis journal ranking, TWM has been named the No. 1 Industry Leader in Engineering in Southwestern Illinois for seven consecutive years by the Illinois Business Journal.
