TSI Global Companies Completes New HQ Built By Droste &Sons and Wiegmann Associates


TSI Global Companies, LLC has completed its newly constructed, 39,600-square-foot headquarters located in the 370 Tech Center in St. Charles, MO. Droste & Sons Construction Company served as the general contractor and Wiegmann Associates was the mechanical contractor. TSI’s new headquarters has 7,000 square feet of office warehouse space available for lease. TSI and its affiliate company, Miami Tribal Systems Integrators (MTSI), will move into the building this month. MTSI is a Tribally Owned 8(a) Small Disadvantaged Business offering high-tech solutions to government clients. 

“TSI Global is excited to be moving into our newly designed, high-tech headquarters facility, equipped with technology test labs, demo rooms, help desk, fabrication shop and training centers,” said Robert Bray, President of TSI Global Companies, LLC. “This new facility will allow us to display multiple system solutions that complement our unique, highly technical service offerings required to continue exceeding our customers’ expectations in this ever-changing technology industry for years to come.” 

TSI Global Companies was just named the 2020 Employer of the Year in the manufacturing/industrial category by the City of St. Charles Chamber of Commerce. For the past 18 years, TSI occupied a building on the same lot of the 370 Tech Center, located along 370 just West of the Elm Newtown overpass. Wiegmann Associates and St. Charles Office Furniture occupy spaces within the same building. Both companies plan to expand into this recently vacated, 70,100-square-foot space to support their ongoing growth.
