Wirrell, Elaine C

Wirrell, Elaine C, a self-certified small disadvantaged business sole proprietorship based in Rochester, Minnesota, provides medical expert witness and case-review services to the federal government exclusively as a prime contractor under a single-customer relationship with the Health Resources and Services Administration (HRSA). Wirrell specializes in detailed medical record reviews, expert medical opinions, hearing preparation, and adjudication support for vaccine injury compensation petitions under the federal Vaccine Injury Compensation Program (VICP) and Countermeasures Injury Compensation Program (CICP). All 53 awards in the source data are designated as total small business set-asides, reflecting Wirrell's competitive posture entirely within the small-business carve-out space.

Customer concentration is absolute and undiversified: the Department of Health and Human Services Health Resources and Services Administration Headquarters accounts for 100 percent of awards and combined potential value across the vendor's footprint, with $8.3 million in total potential value. This single-customer dependency is a defining characteristic of the business. Wirrell operates under three primary BPAs with HRSA. The largest vehicle, BPA 75R60221A00003, carries 22 task orders and $143 thousand in combined potential value. BPA HHSH250201400096B holds 22 task orders and $39 thousand in combined potential value. BPA 75R60219A00083 carries 5 task orders and $11 thousand in combined potential value. A new five-year single-award BPA, awarded June 4, 2026, establishes a $7.5 million ceiling running through June 3, 2031, with an hourly-rate structure: $375 per hour for medical expert witnesses (MD/DO), $175 per hour for medical case reviewers with MD/DO credentials, and $125 per hour for case reviewers with PhD or advanced degrees. Individual order limits range from $125 to $100,000 per task order.

Recent work exemplifies the portfolio: a $11,250 firm fixed-price BPA call issued March 23, 2026, for medical expert services supporting VICP case adjudication with an ultimate completion date of February 22, 2027; a $7,500 call order awarded February 26, 2026, for VICP medical case review work; and an $18,750 call from September 23, 2025, for comprehensive medical expert services including case review, hearing preparation, and expert testimony. Activity has been episodic: one award in 2023, six in 2024, three in 2025, and three in 2026 year to date. Across the entire footprint, only $192 thousand has been obligated against $8.3 million in potential value (2%), indicating a high proportion of unexercised ceiling remaining on the BPAs. Three awards with combined potential value of $38 thousand reach ultimate completion within the next twenty-four months and face recompete exposure. Wirrell has no subcontractor relationships; all work is performed directly as sole proprietor, with primary place of performance listed as Rochester, Minnesota, and administrative oversight coordinated through HRSA headquarters.
