Marathon Technical Services Building

About Us

Principal engineer, Mark W. Thompson, founded Marathon Technical Services, LLC in 1996 after serving more than 20 years as an engineer in the private and public sectors in Marathon County.

At MTS, we are dedicated to offering you the very best engineering design services along with the critical support needed to maintain your utility operations.

Our engineers are the local professionals, with more than 60 years of combined experience in sewer systems, water utilities, and commercial building design in central Wisconsin. In that time, we have assisted in the planning, design, operation and maintenance, of numerous projects in Wausau, Rib Mountain, Rothschild, Schofield, Kronenwetter, Weston, Ringle, Stettin, and beyond.

We have played an active role in the growth of our communities. We have worked on over 30 residential subdivisions, ranging in size from 10 to 400 lots. We are active in commercial and multi-family storm water and site plans, flood elevation determinations and street reconstruction projects. We have recently added a seasoned commercial building designer to our staff. In the past two years, we have designed more than 50 retail, warehouse, office, educational, industrial, and residential buildings.

If you live in or around central Wisconsin, chances are, we’ve worked on something near your home too!
