Gans Hayley

Gans Hayley, a woman-owned small business sole proprietorship based in Palo Alto, California, delivers medical expert services to the federal government as a prime contractor, specializing in case review, expert analysis, testimony preparation, and advisory support for vaccine injury and countermeasures injury compensation claims. The vendor operates entirely under blanket purchase agreements issued by the Department of Health and Human Services' Health Resources and Services Administration (HHS HRSA), competing in total small business set-asides and full-and-open designations. Gans Hayley classifies under NAICS 621111 (Offices of Physicians except Mental Health Specialists) and federal PSC Support—Professional: Expert Witness.

The vendor's customer base is heavily concentrated: 92 of 95 awards derive from HHS HRSA Headquarters supporting the Vaccine Injury Compensation Program (VICP) and Countermeasures Injury Compensation Program (CICP), with a combined potential value of $8.7 million. The remaining three awards, valued at $12 thousand, stem from the Department of Justice Civil Division for expert witness services. Across recent award activity, the vendor has earned thirteen awards in 2022, eight in 2023, nine in 2024, four in 2025, and two so far in 2026, reflecting a downward trajectory over the past three years. Combined potential value across all ninety-five prime awards stands at $8.7 million, though only $383 thousand (4%) has been obligated to date, indicating a pipeline of future task orders against the BPA vehicles.

Gans Hayley holds multiple single-award blanket purchase agreements with HHS HRSA. The primary vehicle, BPA 75R60221A00031, carries a $249,999 ceiling and has issued thirty-eight task orders totaling $217 thousand in potential value. A newer and substantially larger vehicle, BPA 75R60226A00011, was awarded on May 15, 2026, with a $7.5 million ceiling through May 14, 2031, consolidating procurement for both VICP and CICP services. This vehicle represents a recompete win that extends Gans Hayley's direct relationship with HRSA through 2031. Secondary BPAs include HHSH250201400022B (28 task orders, $94 thousand), 75R60219A00035 (16 task orders, $35 thousand), and HHSH250201000047B (3 task orders, $5 thousand). Representative task orders under these vehicles range from $1,500 to $18,750 per call, with firm fixed pricing and performance periods spanning several months to one year. Recent examples include a $18,750 VICP medical case reviewer call awarded September 3, 2026, a $9,375 medical expert services call from August 26, 2025, and a $6,000 expert witness services call from the Department of Justice Civil Division on September 9, 2024. The vendor carries no subcontract footprint and operates as a sole prime across all federal work. Within the next twenty-four months, one award (valued at $19 thousand) reaches completion, posing minimal recompete risk given Gans Hayley's recent BPA win securing VICP/CICP work through 2031.
