February 2017 – TWM is now the 7th largest engineering firm in the St. Louis metropolitan area according to the list released by the St. Louis Business Journal earlier this month. The business journal bases its rankings on number of local licensed engineers, and TWM now has 33.
The top 10 list contains a number of large national firms. Counting only firms headquartered locally, TWM would place 3rd. Over the past 16 years, TWM has forged its way into the top 10 after first appearing on the list at No. 24 in 2001.
