TWM IS CELEBRATING 75 YEARS!

We’re excited to reach this monumental milestone of business success. When TWM was established in 1946, it was a single office with three employees. Since then, the firm has grown to become a top rated firm serving the Midwest and beyond. Today, we have eight offices throughout three states and employ more than 120 licensed professionals and support staff. Together, as one team, we continue our commitment to our clients, people, and communities—all of whom have made TWM what it is today. We’re honored to serve you and as we look toward the future, you can be certain of our company mission and promise to keep providing Exceptional Service. Nothing Less.
