Whitton J Lindsay

Whitton J Lindsay, a sole proprietorship based in Encinitas, California, provides medical expert services and case review support for the Vaccine Injury Compensation Program (VICP) and Countermeasures Injury Compensation Program (CICP) administered by the Department of Health and Human Services as a prime contractor operating exclusively under Total Small Business set-asides. The vendor operates with no subcontractors and maintains a highly concentrated federal customer base dominated by a single agency relationship.

Lindsay's capability portfolio is narrowly focused on specialized medical expert analysis for vaccine injury claims. Work spans medical record reviews, detailed case analysis, expert opinions on causation and disability, expert witness testimony, and professional consultation supporting HHS-HRSA's evaluation of compensation petitions under the VICP and CICP. Representative prime awards include a $7.5 million blanket purchase agreement awarded May 15, 2026, extending through May 14, 2031, under which HHS-HRSA issues individual task orders for specific case reviews; a prior $7.5 million BPA (September 2022 through September 2027) that generated approximately $150 thousand in task orders across 38 cases between September 2022 and May 2023; and a $249,999 BPA awarded April 2021 through April 2026. Individual task order ceilings typically range from $750 to $24,375, with most awards firm fixed price and performance required in San Diego or Encinitas, California within one year or less.

Customer concentration is extreme. HHS-HRSA Headquarters accounts for 341 of 372 total awards (95% of award count) and $28.6 million of $28.8 million combined potential value. The Department of Justice Civil Division holds 12 awards valued at $109 thousand, and the U.S. Attorney's Offices account for one award at $41 thousand. The vendor has registered as a federal contractor since 2007 and has never served any other major federal customer. Activity has declined materially — 48 awards in 2022, 33 in 2023, 23 in 2024, dropping to 5 in 2025 and 6 through September 2026. Five awards with combined potential value of $129 thousand are reaching ultimate completion within the next twenty-four months and will face recompete exposure.

Lindsay operates exclusively under Total Small Business set-asides on prime work. Primary work is categorized under NAICS 621111 (Offices of Physicians except Mental Health Specialists), with secondary classification under 541611 (Administrative Management and General Management Consulting Services). The PSC coding reflects 357 awards under Support-Professional (Expert Witness) and 15 under Support-Management (Contract/Procurement/Acquisition Support). The vendor holds two active IDVs with HHS-HRSA: the May 2026 $7.5 million single-award BPA (HSB114 C 7531) extending to May 2031, and the September 2022 $7.5 million BPA (HSB114 C 7172 and related contract numbers) with a September 2027 completion date. Task orders flow from these vehicles, with the largest parent vehicles showing 102, 75, 58, and 56 task orders respectively across multiple BPA numbers. No subcontract activity appears in the source data; Lindsay operates as the solo performing contractor across all awards.
