Sandip Sen

Sandip Sen, a minority-owned sole proprietorship based in Kansas City, Missouri, provides medical consultant services to the Social Security Administration as a prime contractor, exclusively reviewing disability claim case files to support SSA's disability program determinations. Sandip Sen operates entirely on a full-and-open basis with no set-aside designations across its federal work, competing directly against all vendors on SSA's regional medical consultant BPAs.

Sandip Sen's customer concentration is extreme and immobile. The Social Security Administration accounts for 39 of 40 awards (98% coverage) with combined potential value of $5.6 million across the entire footprint. This singular-customer posture reflects Sandip Sen's role as the exclusive regional medical consultant contractor for SSA's Region 7 office, which encompasses the Kansas City metropolitan area and serves the Midwest/West region. Work is performed in Kansas City, Missouri, and consists entirely of independent reviews of disability claim case files — individual task orders typically encompass between 650 and 1,500 case reviews per engagement. Concrete recent awards include a $252,192 BPA call awarded June 8, 2026 (ultimate completion June 30, 2027), a $194,398 call awarded September 1, 2025 (completion June 30, 2026), and a $136,604 call awarded March 1, 2025 (completion August 31, 2025).

Sandip Sen's work sits on three SSA single-award BPAs. The largest vehicle is BPA 28321321AC0740034, which carries 11 task orders worth $1.4 million combined potential value; two additional BPAs (SS071140030 and SS07164C023) each carry 11 task orders and combined potential values of $581 thousand and $845 thousand respectively. The primary underlying BPA with SSA, valued at $2,667,520, remained valid through February 28, 2026 and established Sandip Sen as the sole contractor for Region 7 medical consulting services. NAICS concentration reflects this medical-services focus: 27 awards fall under "Offices of Physicians (except Mental Health Specialists)" and 13 under "Offices of Physicians, Mental Health Specialists"; 31 awards carry PSC code for Medical/Psychiatric Consultation.

Activity has remained flat — two awards per year across 2022 through 2025, with one award in 2026 — reflecting the rhythm of SSA's quarterly or semi-annual case-file review call orders under its standing BPA structure. Only one award (the June 8, 2026 call) reaches ultimate completion within the next twenty-four months, valued at $252 thousand. Combined potential value across all forty awards stands at $5.8 million, with $3.1 million obligated (54% realization rate). Sandip Sen has no subcontract footprint and holds no parent IDIQs, GWACs, or government-wide vehicles. The vendor's federal footprint is narrow by design — a specialized medical-consulting monopoly in a single SSA region — with zero exposure to DoD, civilian IT, or other customer diversification.
