Zielinski, Mario

Zielinski, Mario, operating as Zielinski Mario, is a sole proprietorship based in Sunrise, Florida that provides translation, interpretation, and language support services to the Department of State as a prime contractor under blanket purchase agreements, competing on full-and-open (non-set-aside) calls. The vendor holds no secondary business certifications and operates exclusively under NAICS 541930 (Translation and Interpretation Services) / PSC Support-Administrative (Translation and Interpreting).

Customer concentration is absolute. The Department of State Bureau of Administration accounts for 22 of 25 total awards (92% of recent awards) and $772 thousand of the $787 thousand combined potential value across the vendor's entire federal footprint. A single Department of State award for language services (not Bureau of Administration) adds $12 thousand. No other federal agencies have engaged the vendor. The vendor operates solely as a prime contractor (100% of awards); no subcontract work appears in the source.

Zielinski Mario holds four blanket purchase agreements with the Bureau of Administration, each multiple-award indefinite delivery vehicle with successive renewals. The original BPA (190PRL18A0346, $100 thousand ceiling) ran through September 2022 and supported FDA investigatory and food security work. Three successor agreements cover language services: 190PRL22A0346 (September 2022 expiration, $150 thousand), 190PRL23A0346 (September 2023 expiration, $150 thousand), and the current 190PRL24A0346 (September 2024 expiration, $250 thousand). The most recent BPA, awarded October 1, 2024, carries a $250 thousand ceiling through September 30, 2026. Representative work includes a $12,360 October 2025 BPA call for language services (completion March 28, 2026), a $5,600 October 2024 call for translation and interpretation services (completed June 21, 2025), and a $10,400 October 2023 call for language support. Historical work also includes FDA assessment investigator services (two calls totaling $10,542 in 2021–2022) and food security support for the United Nations General Assembly 77th session ($2,259 in 2022).

Activity has declined sharply. The vendor received four awards in 2021, six in 2022, three in 2023, two in 2024, and one in 2025. Combined obligated dollars across all awards total $137 thousand against a potential-value ceiling of $787 thousand (17% utilization), indicating most BPA ceiling capacity remains untouched. The sole proprietorship operates with no subcontract footprint and no partnerships named in the source.
