Mgrothaus LLC

Mgrothaus LLC, a veteran-owned small business based in Liberty, Missouri, delivers technical operations specialist, contract specialist, and instructor-led training services to the Bureau of Alcohol, Tobacco, Firearms and Explosives as a prime contractor exclusively under total small business set-asides. The company operates as a partnership or limited liability partnership and competes entirely within set-aside vehicles — all 29 awards in its recent footprint are designated total small business set-asides.

Mgrothaus holds a single customer relationship with ATF, representing 100% of its award portfolio by both count and combined potential value. The company's capability portfolio centers on on-site technical operations support for ATF's law enforcement, regulatory compliance, emergency response, and training operations, including support for exercises such as the Raven's Challenge emergency preparedness drills. Concrete recent work includes a $5,194 technical operations specialist BPA call issued August 24, 2026; an $12,900 contract specialist and technical operations specialist call placed July 14, 2026; and an $11,200 instructor services call completed April 18, 2026. All work is performed on a firm fixed-price basis under BPA calls with individual task order values typically ranging from $4,300 to $55,000.

Mgrothaus operates under two active blanket purchase agreements with ATF: a $500,000 multiple-award BPA awarded January 23, 2025 and running through March 12, 2029 (17 task orders, $226,000 combined potential value) and an earlier BPA carrying 10 task orders valued at $91,000 combined. The company has maintained this exclusive ATF relationship since October 2019. Work is performed at Liberty, Missouri and Huntsville, Alabama. The categorization across recent awards breaks as Support–Management Other (18 awards) and Support–Professional Other (11 awards), both under NAICS All Other Support Services. Activity has averaged between one and six awards per year over the past five years, with $317,000 obligated against $1.3 million combined potential value to date. No subcontractor footprint is present in the source; Mgrothaus operates entirely as a prime.
