ABOUT US

As the 9th largest engineering firm in the entire St. Louis region, TWM provides civil and structural engineering and geospatial services to both public and private sector clients throughout the Midwest and Southeast including Illinois, Missouri, and Tennessee. We draw upon the extensive knowledge, skills, and experience of our licensed professionals, as well as our support staff, to tackle design challenges with accurate and cost-effective solutions. Due to the solid reputation TWM has built over the last 77 years for being able to get the job done right, we proudly retain approximately 95% of our clients’ business. We care deeply about providing our clients with Exceptional Service. Nothing Less.

OUR HISTORY

TWM’s roots date back to 1946 – the year engineer and land surveyor A. Yorker Wade founded the Wade Engineering Company in Belleville, IL, a small community about 15 miles east of downtown St. Louis, MO. An original staff of three worked out of Wade’s home until 1953 when they relocated to a small commercial center the company developed at the intersection of Lebanon Avenue and IL Route 161. To this day, locals still refer to it as Wade Square.

Yorker Wade eventually sold the firm to his son Jerry and another surveyor Bill Moerchen. Meanwhile, Rollie Thouvenot, the younger brother of Bill’s wife, had started working for the firm while still a teen – cutting brush for the surveyors as a summer job. Working his way through the ranks, he eventually became president in 1987, and the firm was subsequently incorporated under the names of those three founders. In 2003, TWM began an Employee Stock Ownership Plan (ESOP), a trust which holds the company stock in each employee’s name, and in subsequent years, the ESOP continued to purchase additional shares. In 2017, TWM became 100% ESOP owned.

From these humble beginnings TWM has grown to the firm it is today, with corporate headquarters in Swansea, IL and 10 additional branch offices. The firm is large enough to take on major projects, but still close enough to its roots to remember the importance of honesty, integrity, trust, and doing business on a handshake. The firm’s ESOP ownership means that every client works with an owner and will benefit from that person’s vested interest in seeing the firm and its clients succeed.

OUR MISSION

EXCEPTIONAL SERVICE. NOTHING LESS.
If you want every employee to know your mission by heart, then make it concise, notable, and bold. If you want them to live it every day, make sure your clients know it and remember it as well.  In 2004 we shortened our mission statement to just four words. We offer those pivotal four words to you as our promise.
