📣 Caught Ya’ Thinking Like an Owner! Join us in congratulating Joseph Esker, our May Employee-Owner of the Month! We're proud to recognize Joseph Esker, Structural Engineering Designer in our Swansea, IL office, for his innovative mindset and commitment to continuous improvement. By identifying opportunities to streamline complex project workflows and applying creative technology solutions, he transformed a time-intensive process into one that can be completed in seconds. His efforts have enhanced efficiency, reduced project costs, and created lasting value across multiple projects—demonstrating the kind of forward-thinking problem-solving that drives TWM’s success.

When asked what employee ownership means to him, he said, "Employee ownership means I'm not just working for the company. I'm working as an owner of it. Every decision I make and every extra effort I put in directly benefits me, my team, and our future.”

🎉 Thank you for all you do and congratulations, Joseph!

Pierce Terrace isn’t just a school. It’s a living lesson in how design can shape the future. TWM helped deliver this 77,000 sq. ft. campus for 325 students, set within a 37-acre site and designed around DoDEA 21st Century Learning principles. This project went beyond classrooms and made the entire campus part of the learning experience.

The project’s commitment to sustainability earned the Special “Green” Award from the Concrete Council of St. Louis. Learn more about our work in this project snapshot: https://www.twm-inc.com/pierce-terrace-elementary-school/

What keeps someone at the same company for 50 years?

For Joe Moerchen, it comes down to the people, the work, and a mindset of showing up every day ready to help solve problems.

From snowy survey fields in the 1970s to today’s technology-driven geospatial projects, Joe’s story offers a unique look at how both TWM and the surveying profession have evolved over the past five decades.
